That is the most concise and understandable information on the wiring of a trinary switch. I just finished putting in a VA system in my car and the videos I've seen fall short of making sense. Thank you
You’re welcome!
Please add more videos.your explanations are very neat and easy to understand. you are very good teacher i ever seen.
We will be working on more of them over the next few months, thanks!
Another great easy to understand video. Thank you Rex.
That was a great explanation on how to wire a Trinary switch. Thank you for sharing.
Thank you, simple straight forward and easy to understand,
Very helpful video explanation! Greetings and thanks from Malta!
Really great explanation. Thanks for the information.
Great video very informative and straightforward 👍👍
Gotta thank you guys for this video. I had no idea where to start with wiring my fans to my A/C system. This was an easy explanation to understand. You really helped me out.
Glad it helped!
VERY INTELLIGENT COHESIVE INFORMATIVE VIDEO LESSON...EASY TO UNDERSTAND! THANKS PROFESSOR
What a wealth of information and yet smple enough to understand very well now! Wow! Thank you. That was great!
Glad it was helpful!
Nice explain 100% 👍 the toggle switch is a great plan
Fabulous explanation. Thanks from OZ.
Really nice job explaining these concepts!
Glad you like them!
Thanks for clearing up all the questions I had about wiring my electric fan into the trinary switch. Darin L. Mandeville, Louisiana.
Glad it helped
Excellent explanation! Thank you!
you're welcome!
Pretty sure I spoke with your wife when I ordered my vintage air system and gauges for my 70 Camaro LS project. I have to tell you she was absolutely wonderful to work with. She was able to sort out the gibberish I expelled and put together the right components the first time, gave me all the normal stuff that’s not in the kit, and all of that which I needed due to the LS swap aspect. Just so you know the whole system is installed and I had all the hardware on the very first attempt. Thank you for a nice knowledgeable and affordable transaction !
I had just a couple questions that you just cleared right up in this simple and straightforward video. I will most definitely be looking to you for further parts and assistance as this project continues. Thank you good sir.
Awesome news, thank you for the update. If you have any more questions, feel free to let us know! - Travis
Excellent Video. The guys at Vintage Air are extremely helpful as well.
Yes, Rick Love and crew are awesome!
Thank you for this excellent video. Greetings from Germany, where AC-systems even in cars of the early 90ies are very rare. Thank you very much :-)
Glad you enjoyed it!
Excellent advice!
This make so much sense thank you. I'm starting to do all the electric work to my classic car
Glad to help
Great video!!
Awesome job showing the wiring.
Thank you!
Excellent Video!! Note: the BLACK wires are wires for the compressor & controller cool thermostat and the BLUE wires for the TOGGLE, BLOCK Sender & high side pressure. Affordable Street Rods THANK YOU!!!
Awesome great presentation!
Thank you!
Thats a great video I understand it now. Thank you vary much
You're welcome!
Super explication thanks
Great freaking video man helped Mr out on my big rig
Great to hear!
good video sir
Thanks a lot sir
thanks for the video,showed me a lot in simple terms,the toggle switch is completely optional right?,just as a back up right?
thank you brother
Great info, great video i have kw w900 ac wires were cut on accident? Ac not working Ac compressor in front of engine 1 wire with ac dryer next to it wire trianary switch all 4 wires cut , have engine harness right their that runs trough engine tru firewall i believe goes to ac control.unit .. my issue is how can I figure out which wires are what ? And how to re wire this unit ? Any advice i would great appreciate it .
I like the way you explained your videos, sorry to bother you quick question you don't have a video explaining how to hook up a trinary switch when you running dual fans I will appreciate the help thanks, keep up the good videos.
awesome info. this was exactly what i needed. sub'd.
Thanks for the sub!
@@affordablestreetrods you mentioned something about brushless fans at the end. did you ever do a video on that? I'm trying to track down a super thin fan for my condenser. i have a holley super sniper with dual fans now on a turbo 302. the intercooler is mounted close to the condenser and i have about 2" max of clearance. my current slim mount fans are about 3" depth. happen to know of any options to add an additional fan? you can look at my most recent video to see what my setup is.
No, we didn't get to make that video yet. The brushless fans aren't super thin unfortunately. We sell Cooling Components fans which are 2 5/8" thick at the back of the motor, I think that the brushless units from Vintage Air are thicker than that though.
@@affordablestreetrods ahh ok. ya, im not sure if i'll be able to find a fan thin enough with my current setup.
Hi where will you put the trinary switch will it go back into the dryer location where the cycling switch used to be on the G-Body Cutlass or will it be installed on the high side line of the compressor to the condenser????
If you're using Vintage Air, then the trinary safety switch can go in the front of the drier. - Travis
Very informative video, I looked through your playlist to find a dual fan scenario with vintage air. Do you by chance have a video in which explains that situation? Thank you.
We don't have one yet but I'll talk to Rex and see if we can get one made and uploaded.
@@affordablestreetrods thank you, that would be very informative.
I would like that as well. Currently in that process with dual fan set up from entropy. My biggest problem is the connect and cruise has a single wire coming out of the fuse box that says cooling fans. Very confused about that
Great instructional video, I subscribed. I used this to wire my trinary switch and stopped at the power wire at the Fan. I have another source to the fan coming from the GM Performance ECM which is relayed and fused internally. How do I properly wire this to work with a single fan where either the ECM or Trinary switch can run the fan?
You'll have to use a 2nd relay to convert the 12v+ to a - trigger, you can see a diagram of that relay here : www.the12volt.com/relays/relaydiagram9.html then you'll have 2 negative triggers for the fan relay and the fan relay can be wired as we described in our video. We like the negative ground approach because if you ever have an issue with the fan turning on, you can simply ground the negative trigger wire of the relay to see if you can temporarily get the fan to run to get you home. It's usually easier than finding another 12v+ source that's fused in an emergency situation - Travis
very nice and simple explanation thank you for keeping it simple. I have a 15" Black Magic fan that uses a sensor stuck in the radiator fins that turns on the fan when 190 degrees. works great but since my system does not use the sensor in the block (only for indication) how do I wire into the black magic fan instead of the engine sensor? Thank you, there is always one of us that has something different
You should be able to use the same trigger wire from your sensor that goes to your fan relay, the same way that the block sender works. All it is, is a path to ground when the appropriate temperature is reached. - Travis
@@affordablestreetrods Thank you. Very simple explanations
Hey friend do I really need to bring the blue wire from trinary all the way to the block sender,can I get by if I just splice into the existing wire thats already there in between the sender and relay ?thanks
So in a car with a PCM/ECU
The wire to the compressor is the switched b+ source from the hvac control panel and instead of a block temperature sensor, the PCM/ECU can switch the ground on at a specific temperature, yes?
Thank you for your excellent presentation. I have a 2005 Mazda MPV ES. The radiator cooling fan it's a dual fan system. One of the fan not working, the other it is OK. The fan that doesn't working has 4 wires. How to test that fan with 4 wires to make sure it's bad?
Unfortunately being a hot rod and street rod business I don't have any knowledge about a later model Mazda product. If both fans have the same style of plugs on them you might be able to swap the plug from one to the other. If you can and the dead fan starts working then you know that the fan is okay and it's a wiring or some other issue. Beyond that I can't be much help on this vehicle. - Travis
@@affordablestreetrods Thank you.
Great/Clear information.
I’m running a sure fit Vintage air on my 68 LS swapped C10 with electric fans. I have a binary switch and AC clutch only kicks in when electric fans turn on. Fans are turned on by computer signal. What are your thoughts on me adding a pusher electric fan in front on AC condenser with automatic start when I turn the ac system on?
I think that you need to change the binary switch to a trinary and use the circuit described in the video. :) it saves you the cost of an extra fan, plus pusher fans and puller fans on the same radiator/condenser often times create turbulence and reduce the amount of air throughput. A good electric puller fan wired off of a trinary as described is the best option.
@@affordablestreetrods I actually already spoke to someone in your store and I purchased the Trinary switch and wiring kit. It was easy install and works great.
Thanks for the help👍🏽
@@argeliogonzalezjr Awesome! Sorry for the delayed response here, sometimes TH-cam doesn't let us know when we have comments. Thank you for your business.
I'm in the middle of an LS swap into a wrangler the GM ecm controls the engine temp fan control. The jeep ecm controls the ac system. We have high and low switches in the ac lines now the compressor turns on but the fan does not. So I'm adding second relay to use with the trinary switch. Do I need to hook up the black side as a redundant system? I also won't be using a separate block sender. So I would go straight from the relay to the trinary switch then to ground? Great video! Best out there. Will I have any issues running 2 relays to the single fan?
You shouldn't need two relays to run the fan, each of the signals that you would send to separate relays can be sent to a single relay unless there's something that I'm missing. I'm not familiar with the Jeep AC lines so I don't know if you'll find a spot that you can add a trinary switch to the system.
Thanks for the vid, very helpful, I'm trying to understand my Trinary switch says it has 3 pressures, 28psi, 241 psi and 398 psi, so I assume, 28-241 are the normal operating pressures (2 none blue) and the other 2 are over pressure. do that sound right ? my thanks great work..
You're welcome! From what you've said I'd say that the switch lets the compressor run if the pressure is between 28 and 398, but it turns the fan on at 241 to try to keep the system in it's "happy place" in the middle. - Travis
Great video! Thank you. Im set up exactly the same as vidoe. At the 4:25 mark, I'd like to tie it into a different location. Somewhere near the fan / fan relay. Is that possible?
Yes, you can tie that line in anywhere that ties in to that ground for the relay.
Thank you for this. My only question is on the black wire going from the trinary switch to the compressor is the ground correct? thanks
The black wires on the trinary switch are for the 12v signal wire from the AC to the clutch on the compressor. The compressor grounds through it's case.
@@affordablestreetrods thank you
Thankyou for your help. I have an 02 silverado . I'm putting electric fans with a delta digital controller. Called a ddc fk75 controller. The instructions tell me to connect controller to the blue wire on the ac compressor. Where is the blue wire at? I thought the compressor had a green wire? Please Help! Thanks, Dale
We don't have any info on what color the wire would be on a 02, but you should be able to trace the wires from the compressor to see what color wire is triggering the compressor.
I have a 70 Camaro with LS swap. I am installing the vintage air now and am at the point of wiring this thing up. I know the PCM sends a ground to my existing fan relay to turn on my fans at 190. My question is, can I just tap directly into the wire coming from the PCM to the ground on the existing relay? Wouldn't this work the same as adding an engine temp sensor into the block or a toggle switch?
Yes, if you're sending a ground signal to the fan relay you can do the same thing with this set up. It will work just the same way as the engine temp sensor or toggle. - Travis
Rex. How much time do I have before I charge the system when I finally hook up all my a/c lines to the dryer? Thanks
You want to do it fairly quickly. If that's not an option then we recommend that you use caps on the lines to help keep extra humidity out of the system. Once a dryer has been opened up after it's been charged we recommend replacing the dryer. It just picks up too much humidity from the air and shortens its life and it's efficacy . - Travis
Might be a good idea to show a fuse between + batt and relay common. Just to show that safety is of utmost concern.
The fan relay wiring kit comes with the fuse already in the wire.
@@affordablestreetrods Just saying that your white board didn't show it. A novice might think the fuse is optional and omit it from the actual harness
@@mr.fredricklawngtawnghedav5094 In order to do that, they'd have to cut it out of the harness, it's clearly shown in the instructions of the wiring kit. Thanks!
@@affordablestreetrods okay. My bad for noticing. Just delete my comment and forget it.
I replaced the fan in my jeep tj with an electric fan. It has the basic ac with high an low switch with orifice tube. The low switch is on the dryer. Would the trinary go in the high pressure switch spot or would it need it's own spot? I am using a manifold temp switch also. Thanks
The trinary should be in the high side, but we do not know of any adapters to make the aftermarket trinary switches mount to a factory mount.
So the other wire on the compressor goes to battery?
Quick question what size wire would you recommend. I try stick to 10-12 Guage but also would you recommend a fuse link or you think it's fine without it.
16-18 ga. is fine for the low amperage loads that turn on the relay, fan wiring needs to be 10-12 depending on application and the fan needs.
How do I put 2 wires safely on to the engine sender thermo ground? And cn I put the trinary ground on top of the fan ground?
Great video! Unfortunately my trinary switch is aftermarket, so my wires are different colors. I have black with white stripe, blue with red stripe, blue with white stripe, and red with white stripe. Any idea how I should wire this according to the video?
Sorry, all of our trinary switches are aftermarket as well, but none of them have that color combination so we cannot be of much help on that one.
Install the trinary switch, put some refrigerant in the system, make sure it's at least 30 psi (low cut out), then test continuity between the wires. The two that have continuity are for the compressor, the other two are for the fans.
CAn you make a vedio on how to mount ac relay and wiring
I'll add that to our list.
Painless sells a fan relay harness #30114 that has a green wire that goes to the ac clutch wire and activates the fans everytime the compressor kicks on , would that be a better way of wiring over a trinary ?
Great question! No, because the AC system doesn't need the fan on at all times that it's running. The trinary tells the fan to turn on when the AC system is at the optimum pressure so it can try to maintain that pressure for best output. Thanks for the question! - travis
I bought the trinary switch, but it doesn’t screw into 96 Impala ss drier?
To fit factory parts like a factory drier, you'll need the factory switch. Aftermarket AC components do not interface with factory ones unfortunately. Because none of the factory cars used the same connections as each other so there was no standard for aftermarket builders to match.
What is the number on the relay switch explain this video, please?
The Fan Relay Kit that we currently sell is found here: www.affordablestreetrods.com/fan-relay-kit-70-amp-510002.html - Travis
What about the trinary with three wires? Please if you can explain it to me
we've never seen an aftermarket one with three wires, all the ones that we have seen have 4 wires. Is this an OEM item or aftermarket?
@@affordablestreetrods I'll explain to you and i hope you can give me some advices, so, i have a classic car with no air conditioner and i bought all the units of the ac but it an OEM item and the pressure sensor comes with three wires, and this sensor sending the signal to the car computer to control the fan and the compressor, but my car it old there is no computer, the question is can i replace it with an aftermarket trinary switch to make it easier to wire it? And if it is yes, is all the sensors comes with the same size?
@@raoufdz7160 Our aftermarket binary and trinary switches are ⅜-24 thread with an o-ring. Depending on what pressure ranges your parts are designed to work at, these might work for you, but we don't have data on the OEM parts so we cannot say for sure.
the compressor dont have to have it individual ground connected ?
I'm sure that I'm following your question. The compressor grounds through it's mounting bracket, which is connected to the grounded engine block. Does that answer your question?
@@affordablestreetrods then why do the compressor have ground a wire?
@@robbwhitehead5486 None of the aftermarket ones that I've seen have had a ground wire. They have only had the clutch engagement wire to tell the compressor when to engage the clutch, turning on the compressor.
@@affordablestreetrods yeah i know this , I think you confused on my question, I was asking after you bind the trianary switch to the compressor hot wire, do I also have to ground the a/c compressor some where else to make it work ? Sense theirs no ground to the compressor to the tiranary switch.
Great video by the way🤙
Would a 2 wire switch wire the same
If you have a 2 wire switch you probably have a binary safety switch and you would need to check out our video on that. If you are running electric fans, you must use a trinary switch instead of a binary switch. - Travis
Thanks I talked with old air products they said I could use the bi nary , wire tge compressor hot to one terminal with compressor wire , and the other to the temp unit
@@affordablestreetrods I didn't tell you I installed a vir eliminator and the 2 wire pressure switch. To my 2nd gen system
Good morning beautiful
You said you can't manually turn the fan on with the toggle switch then you said you can manually turn it on. You made that confusing!
at 6:18 he says you cannot manually turn the fan off with the switch. Since there are 3 ways to trigger the fan, turning 1 of them off will not make the fan stop working if either of the other two methods are creating a ground thereby triggering the relay. - Travis
@@affordablestreetrods oh. Okay 👌
Ck it out
