1989 K1500 Speedometer calibration w/ DIP switches

- In this video, I swap the fuses used to calibrate the speedometer in my 1989 K1500 with DIP switches. I believe this will work for 1988 to 1990 Trucks. The clusters I used came out of 88 to 90 trucks with different rear end and tire setups.

Thanks for the video it was just what I was looking for. I just replaced the tires on my 1988 K1500 Silverado and went from the stock 235x75xR15 to a 31x10.5x15 tire. I removed the 7 fuses and replaced them with the 7 position dip switch as shown in the video. I checked the calibration chart but saw no combinations that was close to what I needed. I did try several of them though. After many tries I finally just turned all 7 on and started turning off different ones randomally (shooting in the dark you might say). After numerous attempts I finally hit on the right combination. For my 3.08 rear gear ratio and the 31x10.5x15 tire it was 4 and 5 off and all the rest on. Thanks again for the information.
That's awesome! Kudos to you for trying all the combinations. I was excited to know that it was even possible to adjust it.
@@MaqsVids It was a lot of trial and error and taking the speedo in and out but I am one that doesn't give up easily. On a funny note my neighbors thought I was going crazy going in and out of the neighborhood testing my adjustments. The speedo is now dead on the money correct.
I'm currently refreshing the running gear on my 89 Silverado (was my stepdad's truck). Speedo has always been wrong so this video should help me get it corrected. Ordered dip switches (2 just in case!) and solder vacuum today. Thanks for your videos and contributing to the gmt community.
Very cool, looking into getting one of these old trucks so this information is really helpful!
Thanks. And, good luck. They are great trucks
Nice work I seem to be having all the same problems with my 89 c2500. Thank you for not skipping through parts that may be obvious to you or that you are doing for the first time and make mistakes like we all do.
Thanks man! I really appreciate it. I try to include details without making it too boring. I prefer 2500s. I had to sell mine because it wouldn't fit in my garage or driveway. I miss it.
Great videos!!! I just started working on an ‘89 Silverado 4x4… it’s a great truck but the dash is all jacked up
Yeah. I love these trucks. My dash is cracked too and all the ones at the junkyard have the same issue....OR..... someone beats me to it.
Great video, thank you for sharing info!
You Are very welcome!
When removing stuff that has the bent over tabs like that I snip from the top side with side cutters. That way you're not having to pry out from the top like you did, which risk pulling the copper trace off of the board. It's annoying that they flip all of the legs over like that. Another thing I do with the solder sucker is that I flow new solder onto the old solder in order to get a better 'melt'. Seems to allow me to get 100% solder removal much easier. Thanks for the video!
That's a great tip! I will use it. I have pulled a trace away from an old board before. It makes my heart sink. And it's usually the last one.Thanks!
I swapped in the wiper motor and a new board from my 1992 C3500 to my 1988 C1500. Couldn't buy a board locally for the 1988 motor. Works perfectly. Now I need to do this DIP switch due to swapping in a 3.73 gear set from the stock 2.73 and have 31x10.50 tires now. Thanks for the video..very helpful.
Nice!!! You are very welcome. I love these trucks and the more that are out there the better.
this was awesome... thank you
You are very welcome!
Thanks man, very help full.
You are very welcome. Good luck if you are working on one.
@@MaqsVids i actually have 2. Both are 92 modles, the one i just bought has some problems. Hopefully the fuse thing will solve one of them
Thank you, much appreciated
You are very welcome.
Yeah music 🎶 is smooth thanks
Great video. You are the only person i have found on TH-cam that addresses this issue. I feel brave enough to tackle this project now. My speedometer shows a slower speed than i am actually traveling. Do you have a part number or Amazon number so i can order the part? Thanks again much appreciated.
Thanks! There is a link in the description to the switches I used. Good luck man!!
What year windshield wiper motor did you replace the old one with?
Great video, can you please tell me where in the US I can get the DIP switch? I’m in Australia and have an 89 GMC that the Speedo is way out as I have changed diff gears and wheels.
Thanks! I updated the description with a link to the DIP switch I used. Newark.com is a site I use often. I should have done that from the e start. Good luck!
@@MaqsVids thanks mate, I found some down here and just ordered a few, I will get someone with some soldering skills to instal it for me, you’ve saved the day 👌🍻
Hey bud AWESOME video. I'm glad I found your channel cause I have a 1990 model obs. I was wondering if you know how to check if the speedometer gage is working because my speedometer and odometer are not working. They never worked when I purchased this truck. I replaced the speed sensor and it still isn't working. If you have any suggestions on what to do to get it fix I would really appreciate it.
Hey! Thanks!!! My odometer didn't work when I got mine too. But, I have not fixed a broken speedometer before. I wouldn't be surprised if it is something with the cluster. These trucks are simple compared to modern cars. It could be something simple. I did fix my odometer with a new gear though.
@@MaqsVids thanks for replying so soon. I took my cluster apart and checked the odometer gears and I was able to spin the gear and when I did the numbers would move so I think my odometer gears work. I think they are not moving because my speedometer gage isn't working. Is there a way to check if its the cluster that isn't making my speedometer gage not working. Is there a way to check it ?
@@supamario830 There has to be a way. But that is beyond my knowledge at the moment. Do you have access to another cluster?
I know this is an older video, but my question is, can you install the dip switch from the other side so you don't have to take cluster apart to change settings.
🤔 I don't know. But that is a good idea. I will look into it. That would be nice.
So using these dip switches is it not necessary to reset the programming like the kit did back in the day? I'm talking about where you plugged the harness from the kit into the cluster and sent 12v across
I was going to go to a junk yard and find an old cluster harness to make the reset harness but if these dip switches negate that step that'd be sweet
That is the first I head of a kit. I didn't have to do any of that. Once the switches are set, you are good to go.
Ok cool I'll give it a try. Yeah back then GM sold a kit it was a harness you plugged into the cluster to reset the speedometer. After that there was and 8 pin connector what they called "programming clip" that plugged into what you desoldered. Based on axle ratio and tire size there was a chart that would tell you what pins to remove and then you'd plug it into the back and good to go again. They discontinued that kit long ago so good luck finding one anymore. This is the best solution i think. Thanks a lot for the video!
Where'd you order the dip switches from?
@@cast-ironcowboy I ordered them from Newark.com I'll look at my order later if you want the exact ones.
ive got a 98 1500 and my speedo is off in a non linerar way, that at 50kmh it reads 70 and at 80kmh it reads 120. would something like this work for my truck being so much newer and would this fix my issue of it not always being off by the same amount?
I'm pretty sure yours is different and a bit more modern. I don't think this will work🫤
@@MaqsVids ah alright I’ll keep searching thanks tho and really well formatted video
If you find a 91 cluster with needle guages they are alot more reliable/acurrate...only year they are plug and play for the moon guages
I didn't know that Thanks for the tip. If I stumble across one I may play with it
wheres the link for the dip switch settings
It's in the description. But I'll put it here too. Scroll down 67-72chevytrucks.com/vboard/showthread.php?t=313815
Hey, by any chance, would you make me a board. My soldering skills are subpar at best
If I can score a another cluster I will. I would hate to mess up your only cluster. I had extra clusters so I wasn't afraid to mess up.
@@MaqsVids or call me, 651-219-3391
I will just drive 10 miles slower. And save me all that work
Now I am jealous. You are lucky to not suffer from an addiction to Tinkering. I can't help myself.😉
And, It was not always a 10 mph difference. At zero it was dead on and as I sped up, it got worse.
