2019 GMC Sierra Denali Radar Detector & Dash Cam Hardwire Mirror Tap
ฝัง
- เผยแพร่เมื่อ 3 ต.ค. 2019
- I recently got a 2019 GMC Sierra Denali Ultimate and it was time to install my Max 360 radar detector and Street Guardian dash cam. I always like to hardwire and integrate my accessories for a clean install. I hate having wires running to cigarette lighters, so sloppy!
This tutorial will work for 2020 Sierra/Silverado models and even earlier ones. In fact it will work for any car, because I'm going to teach you how to find switched power and a good ground. You will learn multimeter basics and wire up any device easily. This guide will also work with any brand of radar detector like Valentine 1, Whistler, Unident, Blackvue, Garmin, and more!

Hello Dmitry - thank you for your great, and simple, explanation of how to install a mirror tap. You instructions and video worked perfectly on my 2021 Chevrolet Tahoe. The connector wires are still the same as what you showed. Keep these great tid bits coming. Really appreciate you taking the time for us novices out here. Take care.
Thank you for taking the time to show us how this is done!
Just wanted to let you know you saved me a lot of work. I have a 2020 Silverado with the same mirror as yours. I simply took the plastic off and inserted the pins into the colored wires you tested and boom finished. Thanks D-man
Great to hear it Randall! Will help others know this is compatible with the '20 Silverado as well :)
Thank you for your video! Took less that 15 minutes to finding the correct wires and having everything back in place. I used the extra harness and powered right up.
Glad to hear it Seven!
Great video. Went straight to the plug and 1st two wires I tried were correct. You save me a ton of time. 2023 Sierra Denali is purple/black now, not purple/white.
Thanks for the video. Everything on my 2020 GMC Denali Ultimate was exactly the same as in the video! The only difficulty I encountered was getting the connector behind the mirror separated. The is a push release on the top side that has to be depressed to release the connector. Great video! I appreciate you putting this together!
Thanks Steve, glad you liked the video. Thanks for sharing the details on the plug. Hopefully it helps others :)
2021 Yukon Denali...watched the video. Very simple and clean install. Thanks!
Thank you. One of the best DIY instructions I have ever seen. Any dummy can follow this and get it done. Clean job.
Glad you enjoyed the video and my instructions :), I like doing a bit more background than just "hey here is where I plugged it in". I think it's more of a "teach a man to fish" if I show how I figured it out.
Worked great on a 2021 silverado LTZ. Same connector as in the video. Very easy install. Thanks for your video.
Awesome, thanks for confirming that William, will help more people out to know it works :)
Thanks Dmitry - this worked perfectly on my 2021 Chevy Blazer. Same wire colors. I appreciate the video!
Thanks for confirming Dave! Glad it helped :)
Awesome video, thank you. Just installed my mirror tap on my 2022 Sierra Denali hd following your video! Spot on
Clean look and great integration! Hoping to try this on my wife 23 Tahoe here today with the help of this video and a couple instructions from the forum!
Glad you liked the video! Good luck on the install, you should be able to use the techniques on any car. I bet the tahoe is probably quite similar though.
Thanks for the video!! I just installed this exact radar setup in my 2020 GMC Sierra 2500 Denali and the connections and mounting are exactly the same. Worked perfect!
Glad I could help Jeff! Thanks for letting me know it works on the 2020 Sierra 2500, helps to know the compatibility. Appreciate you watching.
@@DmitrysGarage is this radar for cops?
I don't have this vehicle but I appreciate you sharing wire testing methodology that can be applied universally
Glad I could help!
Just transfered my blend mount and wire tap from my 2015 3500HD LTZ to my new 2020 Denali HD... Super simple, compatible and I didn't even have to test anything... Purple/ white positive switched ignition and black/white ground just like you showed us... THANKS..!
Glad it worked well for you Bob! Thanks for watching!
Is the 2015 Sierra very similar?
Awesome how-to, Dimitry!! Very well done!
Thanks for watching and commenting, it’s appreciated!
Thanks, going to be installing this same setup this week.
Thank you video, I bought the product from your link and just installed it. Your video made it a beautiful and easy process
Thank you for watching and commenting, I really appreciate it!
Thanks for the vid. Very useful for my install on my 2021 blazer
The gen5diy harness is perfect. I have used them in a 2019 and 2020 Silverados both LTZ with the camera module you have in your GMC. I highly reccomend the product you put in the link. And, thier customer service is amazing if you need help.
Thanks for the video, i finally got my radar detector installed
Glad I could help! Thank you for watching!
Well done! I'm doing mine today. Thank you for the content
Thank you Eric, appreciate the kind comment :)!
Awesome video! Saved me a lot of time and answered several questions. 👍
Glad to hear it Mark, it's why I do it :)!
Great video thank you so much you save me from having to pay for this installation. I currently have a 2019 GMC Sierra AT4, it worked perfectly.
Glad to help Julian! Thank you for watching!
Do you need the mirror to have to camera option for this to work ?
Thank you buddy. I was able to quickly do this on my GMC AT4
Glad to hear it!
Thanks man, that was exactly the same mirror set up as on my 19 Silverado LTZ. Same wires and very nice how easily those covers come off.
Glad it helped! Thanks for watching!
I hope its the same on my 2020 ltz, gonna try it tomorrow.
@@dankane8625 was it the exact same???
Great video. Detailed and concise.
Thanks!
thanks for the video, just did the mirror tap using your instructions!
Really glad it worked out for you! Thanks for watching
@@DmitrysGarage Got the same truck in black! hope you do some more mod's!
@@tcrrider142 Yep I may do a few more things with it at some point. I think I'm going to keep it for a long while.
Thank you Sir! Appreciate the detailed info.
Thanks for watching!
Thank you my instructions didn’t match the color code of harness. My harness matched your install. Thanks for sharing
Glad I could help out! Thanks for watching :)
Thank you for the lesson sir, nice video!
Glad you enjoyed it John, thanks for watching!
Great video and information!
Thank you for watching, glad it help!
Worked for my 2020 high country.
Fantastic video very informative thank you sir 🍻
Glad you enjoyed it
Me and my cousin did this on his brand new 2024 AT4 Duramax not even 10min thanks.
Nice video but for newbs I really wish you would’ve gone through how you made your little harness and which one you bought. Plus more about how you connected it to your camera.
That's really nice
great tutorial
Thanks!
@@DmitrysGarage Hey so I tried doing this a few hours ago and I cant get the pins inside the connector! I tried both the small pin (which got bent) and the larger pins dont even fit... Feel kinda dumb now maybe I'll try again next week when I'm off work
Great job!
Thank you Jiahua! Appreciate you watching!
I need a new mount I hate the racket the default mount makes. Constantly sounds like metal pieces banging each other. What would it have killed them to add some foam
Well I went to your product links looking for the alligator clips with the 90degree needle tips... no luck
When you said the mirror plug looks the same as the older trucks, are you talking about the k2xx 2014-2018 models? If so, do you know if the actual mirror physical mount is the same as the old models? I would like to retrofit the rearview camera mirror in my 2014.
what "pins" are you using on the wiring connector (that you insert into the back of the plug)?
Thanks for the video. My 2011 Toyota Sienna I've installed similar way camera has permanent power source so I can use parking mode, but my gmc look like work only when engine is on.
Glad you liked the video. Yea the goal in the video was specifically for a “switched” power source. I specifically wanted one that only turns on with the engine. You can use the technique shown to find a constant power source. However, I also know that there are tons of fuses with constant power in that truck. Should be very easy to use a fuse tap.
Good content thanks
I love the tail gates on these trucks, how do the people that have them like them? I don't have a 19/20 yet, mine is a 2018 with only 31k miles. I got offered really close to what I paid for my truck but there are no new ones available
what is the usb mini cable you used there my Rexing uses usb mini too
Would this be applicable to a 2011 GMC sierra 1500? Thank you.
Hello Dmtiry, thanks for your help on this. I have a question regarding the Gen5DIY adapter you recommended.
The mirror tap has a ground and switched power (red). What are you doing for the yellow/constant power from the dashcam side hardwire kit? Or is not unnecessary at that point?
The constant power wire is for dashcams that are meant to run while the vehicle is off. Mine is setup for switched power as I dont really park anywhere unsafe very often or for very long. If you don't need the constant power you can just isolate it so it wont arc on anything I imagine.
So I am looking at doing this in my 2020 GMC Denali. I have looked at the wiring harness. I am confused if I would just push the pins directly in the slot behind the ones you stated or in the same slot with the colored wires? Thanks in adavance.
You can just push the new pin next to where the correct wire comes in at the back of the harness. Like as if you were pushing the factory pin back into the harness.
good stuff
Thank you for this!! Was hoping to do this exact thing for a dash cam. Did you just push/force the wiretaps in or did you do something off video that spliced them together?
Hey, glad it helped. You can force the pins in if you have the right taps or just splice as you would normally into the harness
Thanks, I'm thinking of trying this on my 2020 Suburban. I would have liked to see where the wire comes out of the housing to the dash cam. Did you drill a hole or run it under the edge?
Glad you liked the video. I just ran the wire through the existing gap, it was plenty big and let the cover snap on without issue. On some cars i have cut/drilled
Excellent video, how exactly did you attach the wires from the camera to the mirror plug?
Thanks! I used pinned wires that have a thin flat pin on them that jams into the harness firmly.
How the hell did you smash another pin in the connector? I can’t get anything in there to save my life. Really hesitant to splice into these wires
Have you done a 2019-2021 Sierra without the camera package? What fuse do you use in the panel. I have a 2021 Denali but didn’t get the rear view camera package and want to hook up my blackvue camera. Thanks
I have not, but if there is 12V power there you could find it using this method.
Great video. What be possible to take a picture of the right side of the mirror where you have the dash Cam mounted?
Victor, hope this helps: imgur.com/X27Pkdf
Thank you
How did you assemble your listed adapter to have a mini usb attached? Was it as simple as splicing it in or do you have a Fuse in that line as well? Thanks for great video btw
Thanks for watching Calvin! Yep I just spliced it in, super easy just look up a usb wiring diagram. Use your best judgement on fuses based on your load and risk. I did not add an extra fuse personally, riding the cars built in fuse for the circuit. In this vid I mainly wanted to show where switched power is on these trucks and also how anyone can figure it out like I did on any car.
Thanks for the video I need to do this for my 2019 Silverado. I see the RJ11 is for the radar detector but I’m only installing a dash cam. Did you strip the dash cam wire to connect to the mirror harness?
Thanks for watching! Exactly, I just spliced together the RD and Dash Cam harnesses.
Dmitry's Garage thanks I’ll give it a shot! Not sure how you’re the only applicable video I’ve found on this! Great job
@@Smaulls It's a new and fairly pricey truck, I think a lot of people buying these new aren't going to be the first to try and DIY something like this without a guide. Luckily I'm crazy enough to be first :). I watched some older model ones and YOLO'ed it! In reality someone has to be first and this is how products get developed. Someone in that market busts out a multimeter on a borrowed truck and figures it out. I just had to buy my own to do it hahaha.
I have a new Silverado with the same mirror. I have a Cobra dash cam with both front and rear cameras. Is there a way to wire it and use the camera mirror as the rear camera instead of running the rear camera that came with the cobra? Thanks, Randy
Good question Randall. In theory I think anything is possible, however I doubt there is a practical way of doing what you seek. There is going to be the question of how the signal is fed. Is the cobra expecting a digital signal or an analog signal? Analog signals are easier to split, but I'm fairly certain the truck uses a digital signal. If both use digital signals and they both used the same encoding (i.e. TMDS like HDMI) you could theoretically split the signal i.e. think $10 HDMI Splitter that mirrors a signal to two different TVs or monitors. You'd send one back to the truck and one to the cobra. The challenge there would be media conversion. Neither the cobra or the truck are likely to use an HDMI cable that could simply be unplugged and split via a splitter from Best Buy.
If we assume the truck and Cobra signals are compatible the challenge of tapping will be figuring out what media (cable) the mirror uses to send the digital signal to the truck's infotainment system. Once that is established you would have to figure out how to get in the middle of it (i.e. disconnect it at one end). Then you would have to convert it to a media that can be split by an off the shelf $10 splitter. Then coming out of the splitter you would have to once again media convert both ends to match the truck and the cobra.
In an ideal world the truck would just let us record all its cameras to an SD card in the glovebox. Or at least offer an HDMI output that we could connect to a video field recorder. Without either of those options I honestly think you will have a much easier time just running the cable and camera the Cobra came with. This is an interesting thought experiment though.
EDIT: Just for fun I googled to see if GM was working on anything like this:
The Surround Video Recording System, sometimes referred to as Surround-View Video Recording System, is a General Motors technology that enables users to record video around their vehicle to enhance situational awareness, safety for the driver, as well as vehicle security. Captured footage is stored on a standard SD card in the trunk of the vehicle. Owners can choose to save certain captures indefinitely on the SD card or they can view or save the video files onto their personal computers. The recorded videos can also be played back while in the vehicle.
Currently, the only GM vehicle that offers the Surround Video Recording System is the Cadillac CT6.
Hey , how did you make braket to connect it to the mirror and connector for wires? Thank you very much
Anatol, not sure what you mean bracket wise. The bracket holding the camera is made by the camera company, it is held on to the windshield with 3M tape. Is that what you mean?
The algorithm put this in my feed. I have a question that I haven't seen directly answered anywhere. Does the Live Feed mirror simply need a switched 12v and ground to operate? I want to install in an older GM vehicle. Thanks in advance!! Appreciate this video for its information and simplicity as well.
Thanks for the kind words! I have not tried doing that, but I suspect it needs more than power. I believe it will need whatever other harnesses/modules it uses to get the signal from the rear camera. It also doesn't use the lift gate camera, it uses the one on the back of the cab. Not sure that camera comes on the non-live mirror trucks. I would imagine this is a quite intensive installation to make it work.
@@DmitrysGarage I was talking aside from the proper camera and camera harness. I believe they may have up to three different ones, if memory serves. Backup camera, live view type and bed camera for some trim levels. My theory, so far is that the mirror needs a 12v source to allow it to power the video feed and camera going out back, I just can't seem to verify that at the moment
Yea I'm really not sure either.
Went to do this in my 2021 Yukon Denali that has the same setup and it did not power on and now the rear view mirror camera (not back up camera, but the one inside the rear view mirror)isn't working. Before taking to dealer and thoughts?
Are you sure you didn't trip a fuse? I would check all fuses and the harness connection first, disconnect any custom harness you may have added in case you have a short there. If you were using a multimeter you could do some continuity testing as well. I'm not familiar with the 2021 Yukon, was the wiring the same otherwise? If it all looked the same, same color wires, then I'd suspect a short/blown fuse first.
Do I need to use this specific radar detector that you have listed or does most work
The method outlined should work with almost any radar detector
Do you happen to know what mirror tap I’d need for a dash cam only? I have a blackout dr900s 2 channel. Not using radar so only need to get power to the camera. This looks like a better solution than the cigarette plug. Thanks for any info you can provide
David, thanks for watching. I kind of built my own from parts I had. I would recommend either tapping/splicing in or buying an assortment of taps (amazon has kits) and seeing which is just the right size.
Dmitry's Garage I ended up doing a fuse tap. I have a power magic pro that I can turn on for parking mode.I wanted parking mode since I have a BlackVue dr900s. Accessory fuse tap went to the heated steering wheel, constant power fuse tap went to the universal garage opener fuse. Ground was right under the fuse panel.
how did you secure the voltage control box? Zip tie behind the mirror?
Rick, thanks for watching! I used a piece of 3M VHB tape (amzn.to/37iTtqO) to stick it to the back of the blendmount where you can't see it. It's really strong stuff.
Question, how do you power a USB type dash cam off a 12 volt circuit
Thanks for watching I use something like this: amzn.to/2IAyqWG
Does the dash cam wire step the volt up? i tried this but it i does not power my dash cam
Dash cams run lower volts, you need 12 to 5v step down if your cable doesn’t include it
Interesting how the switched 12v lead doesn’t get power at the connector until the car is on. On my 2021 Tahoe I’m finding that every fuse in the panel is hot. Looks like GM May be using the ECM to distribute the power to the end connectors. Makes for a harder time when trying to wire both switched power and constant power for parking mode on my dash cam. Might need to wire switched power to the mirror as you have and run another lead to the fuse block for constant power.
I found the same thing on my Sierra. Every fuse is hot at all times. I think they're just essentially running a digital power supply and supplying power as needed vs. using traditional relay/fuse.
Look at 1min,30sec on this one. I think it may help you th-cam.com/video/idebIVG6cho/w-d-xo.html
Really hope you can help with a question that I have; Is it possible to run two mirror taps connected to the same location if it fits? I want to be able to run my dash camera and radar detector using mirror taps but without causing any damage to my car. ??
You can run two devices off one power source. You should double check how much amperage they draw, but most radar detectors and dash cams draw way less than even 1 amp. As long as they're small electric loads it should be safe to tap in there.
@@DmitrysGarage Thank you...
Thank you for this!
I used the uniden radar detector, what dash cam do you prefer
I recommend this Viofo dash camera: amzn.to/4aFx7BU
This has one of the newest best low light Sony sensors for these kind of cameras. The sensor can also do true 4K unlike cheaper sensors where the 4K is faked by up-scaling 2k or 1080p.
I hooked mine up just like this but I loose power when slecting reverse.
That's really weird. What model vehicle? I heard from someone here the new ones have a different color scheme. I always recommend testing with the multi-meter though!
Will the dash cam work while the truck is off? Just in case somebody bunk into your truck?
No it will not unless it has a battery since that power source turns off.
This worked for me but I had a heck of a time getting my ferrule pins to stay in the wiring harness. I pushed them in pretty hard but there was no friction in there and the pins would just slip back out again. I tried sharpening the pins to a point and that didn't really help. I couldn't think of another good way to keep tension on them to keep them secured. It's working but I'm afraid that I'll hit a bump and lose the connection. Did anyone have this issue and what did they do to keep those pins tight in the harness?
Bryce, I think the big challenge is having the right size pins. If they're too thin they fall out, too thick you can't push them in. If the connection is too loose you may want to employ another tapping method like a splice and crimp + heat shrink to isolate it.
@@DmitrysGarage The RJ11 Power Mirror Wire Tap from Amazon actually included to jumpers that wedged nicely into the back of the connector.
Will the Dash cam work while engine is off? In this set up???
The goal was to find switched, not constant power in this vid. So no it won’t work if the vehicle is off.
Wondering if this works the same in a 2019 GMC Yukon Denali?
Probably will if its the same mirror. Ive had a lot of people confirm in other GMs. If you have a multimeter you can always figure it out like in the video.
And you connected the ground extension to what/where?
The extension is just connected to the battery negative terminal, it is for testing only because it lets you have a known good ground so you can validate switched power AND find a good ground near the switched power (which I also showed in the video). Hope this helps!
Is it the same on gmc sierra slt 2019? Thanks
Another viewer said it worked for his mirror in his 2019 LTZ, so it may be the same. However, using the method I showed in the video you can find a hot switched wire in any vehicle :).
Did you use a 12v to 5v convertor?
Yes, you do need to use one for that dash camera. I tucked mine away.
Thanks, maybe at the beginning you could quickly say p/w hot, b/w ground. That's all i was looking for but thanks tho really.
Good point but to be honest I was figuring out the pinout as i shot the video. I was sure it was there but didn’t know before i started shooting which wires. I learned as I made the video.
Where did you hook up the temporary ground wire to start this install??
The battery negative terminal under the hood, which is the ultimate ground for the entire vehicle. I explain this at 2:30. Thanks for watching!
@@DmitrysGarage There is a ground near the kick pillar if you are writing down to the fuses anyway.
Any fire risk with tapping into the mirror like that?
Just make sure the wiring is secure and the tap is secure. You dont want anything rubbing through and grounding or jiggling loose and sparking. Otherwise as log as you keep factory rating fuses you’re fine.
Hey, I live in the Houston area and plan on buying the 2022 GMC Sierra Denali Ultimate and I want to have a dash cam set up. Can you do this set up for me and if so what would you charge???
Thank you for watching my video. Unfortunately I don’t really do this as a day job, otherwise I would absolutely help you out. I would recommend any reputable automotive audio shop to do this kind of installation, it’s a simple job. I bet even big national brands like Car Toys would do it.
@@DmitrysGarage sounds good, this video brought me to your channel and u have a lot of good content! Keep up the awesome work!
Sorry if I’m dumb but do you by chance have a video installing the dash cam with it?
Nick, unfortunately I don't but really it's very simple. You just need the little transformer kit to step down the nominal 12V to the 5V USB power the dash cam needs. It's just wiring two wires (hot/ground) same as the radar detector. Those kits can be found on amazon, just look for dashcam hard wire kit 5v 12v.
@@DmitrysGarage hey thank you so much for the reply, can’t say I’ve ever had someone actually reply back with advise. So it wires in the exact same ports as the radar detector ? Also how do you like that detector & would you say it’s worth the almost $500 price tag? I’ve had cheaper units in past and honestly got more false reading than positive.
@@nickbryant6472 No worries. Yep, they use the same pins. The radar detector and dash cam in my video are on the same "circuit" meaning they both share the same hot and ground wire for power. That detector is pretty good, I've had it for a few years now. I am intrigued by the Uniden R8 as well. False alerts are going to happen, unfortunately that's just part of the game. You start to learn the difference in how the signal ramps, the directionality (arrows), and interpret the severity of the threat. This one has GPS lockouts so it will block the K band radar sources it sees repeatedly which keeps it quiet once you've driven around a specific area a few times.
@@DmitrysGarage hey back again, I’ve been super busy but saved up some money and I’m curious if you had to buy a detector/dash cam again today would you buy these same products or is there a newer product you would go with ? Thank you again in advance for all of your advice and help it’s really appreciated!
Thank you for the video Dmitry!! I just made a harness like yours and installed this in my 2020 AT4 thanks to your video. One question for anyone... where is best to route the wires from inside the plastic housing? I went along the mirror cylindrical beam, but it felt like a tight squeeze. Did anyone file down a little tunnel/arch on the plastic? Thanks!!
Thanks Jonathan, glad you liked the video! Yea that's basically how I did it, along with the mirror beam. On other vehicles I've filed down tunnels, sanded and even painted to match. I usually see how much the part I want to ruin is so I don't ruin anything expensive. That way when I sell the car I can just replace it. On the Audi I had I filed it down because it was a $20 part and the squeeze was too tight. I think it just depends on the build tolerances of the parts, the Audi wouldn't let me put anything around the plastic, it was either a perfect fit or no fit. With the truck I could still snap it back and have enough room for the cables to get through. If your harness is thicker you may want to consider the tunnel, I doubt it's a super expensive part. I just wouldn't want a future buyer to be like "oh man what's this stupid gap in the plastic?
ahh never mind, it was just one of those camera blips that come with the denali's
Glad you figured it out! Hope mine doesn't start to blip, hahah.
Can anyone say if this will work in a 2022 Chevy Silverado 1500? The cover looks the same but haven't pulled it down yet to look at the wiring and plugs behind. Hoping they didn't make changes for the 2022s as I have to have a radar detector haha
I'm really not sure. I would assume it is, if the wiring all looks the same color and pin wise you're probably good to go.
@@DmitrysGarage it does work! The pin wiring was the same. Plugged in according to your video and it works just fine!
@@drewandashleybenson9752 That's awesome! Glad it worked for you!
@@drewandashleybenson9752 Since your install on this, how has it been holding up? Any issues with the radar detector or mirror? I'm thinking of doing this to my 2022 GMC Sierra 1500, but I've been hearing mixed information on whether it can be done on the 2022s or not.
@@gagerutledge4620 hey there. I tapped the mirror the exact way the video described and so far, no issues with the truck at all, or the detector. Rear view camera mirror still has a great picture and the radar detector has of course saved me from lots of tickets already 😬
No regrets on giving it a shot on my Silverado! Good luck

Where can I get those pick leads? Is there a link?
Nick, I got the picks locally from Fry's Electronics, but something like amzn.to/2YiK7si or very similar to it would work. You probably don't need such a huge kit.
Dmitry's Garage thank you sir.
i hooked mine to the purple and white and now the rear camera doesnt work ? did you have this issue ?
Hmmm like the rear view mirror or the backup camera? I have not had any issues with my setup. I don't believe it would affect the backup camera since I'm not sure how that could remotely be the same harness. However, the rear view mirror needs to have a good connection, so if that is what is broken I'd check that the harness is plugged in well, if you spliced I'd make sure the splice hasn't broken the connection to the harness. EDIT: I'd also make sure you didn't short out anything, i.e. blowing a fuse from touching the hot and ground.
@@DmitrysGarage Same thing happened to me. Do you know which fuse the 2021 Yukon Denali Rearview Camera is? The manual is very hard to read with all its abbreviations.
@@chadhenman9936 Ben I really don't, since I only have the 2019 Sierra Denali. I would suggest testing each fuse. This is quick if you have a fuse tester, if not you might have to yank em out one at a time.
@@chadhenman9936 Ben, did you figure out what caused the problem with tapping into the purple and white wire and the rear camera issue? I just purchase a 2021 Yukon AT4 and want to connect my radar detector to my mirror that Dmitry demonstrated, but now I am concerned and hesitant!!!
Hi Robert, did you figure out what caused the problem with tapping into the purple and white wire and the rear camera issue? I just purchase a 2021 Yukon AT4 and want to connect my radar detector to my mirror that Dmitry demonstrated, but now I am concerned and hesitant!!!
Is there a constant 12V signal in that mirror harness?
Not one that I found while making the vid, but I stopped testing when I found a switched source. There are tons of always on 12v fuses you could tap.
@@DmitrysGarage Yea but much like yourself, I wanted to contain all the wiring (this request was for the 24/7 dash cam function specifically) within the mirror housing so I didn't have to run anything down the a-pillar.
@@brianpyun9388 I understand why you want to contain the wiring and the need for 24/7 dash cam surveillance. You should be able to use the testing methodology in my video to see if there is a constant 12v source there. Wish I knew the rest of the pin outs, but I just dont.
@@DmitrysGarage I was thinking about it last night, if the mirror doesn't the onstar def will. If I find something, I'll report back.
@@brianpyun9388 Yea that makes sense to me, let me know what you find!
Awesome video, thank you.
Just an FYI the dashcam link is now dead, please update so we can use your affiliate link.
How did you wire the dash cam or did I completely miss that?
Thanks for the heads up, I'll get the link updated. I'm glad you enjoyed the video. The dash cam is wired just like the radar, it's just positive/negative, nothing special.
Anyone had any luck on a non-powered mirror? I don’t have the wires that he was talking about in my truck.
Jonathan, does the mirror have no power at all? If so you'll need to find another 12V source. If it does have some power (i.e. for compass or similar) I would recommend snagging a multimeter and following the tutorial part of the video to find the correct cables for you. You can get a VERY good multimeter for under $40. amzn.to/3hp1nI0
So I don’t have the power mirror, but I have the camera power box. It’s that silver box you describe in the video. Would I be better off hardwiring it in or can I still tap to the wiring around the mirror?
I would not try to tap the camera as I believe it is used for collision mitigation. I would avoid messing with it. Its also probably not 12v they’re usually lower voltage. If theres no other power there you may need to tap a different switched source. There are some fuses on the passenger side as I recall that may work.
You would think that with all those cameras on the GMC’s they would work like a dash cam.
Ho,y crap! You look exactly like John Candy!
Hahaha, haven't heard that one, but I see it now haha.
It’s a plug & play wiring harness that uses the factory connections. All of this is unnecessary. Just buy the harness and you can mount your detector in about 10-15 mins.
I mean there was only one for sale on the market when i made this and its like $75. Sure you can buy it, and I even linked to it. However learning a skill (finding switched power/ground) or even just doing something yourself isn’t unnecessary just because you can pay someone else to do it.
Go on the other side and use the red and orange. A lot easier to put your tabs into
