Hi, I did lift pin 3. It was a grey/green and folded back in the picture below. All the other wire colors and positions match your posted table above. Any ideas I'd be very interested! Thanks

This is actually a datalink wire.  I’m a bit concerned about what other messages we are not allowing to be sent through with this mod.

Hopefully the vid works, but that's a full brightness and full dim and can be anything in between with the actual dimmer wheel.. I drove it tonight and noticed when I had the gauges full dim then put it in reverse it never got brighter then dimmed it just stayed dim and I loved it haha its the simple things in life

Did some digging through the "2015 Sierra Silverado Electrical Body Builders Service Manual," and found a similar page to the Colorado's on Pg 628, for those that have it.

Did this mod on my truck yesterday, had the chance to try it out tonight works great. So much better and now I can dim the backup camera with dimmer wheel. Glad I found this thread.

Does this end up locking/ put it into a theft mode on the stereo once you disconnect the plugs in the back? 

I ask cause of my '13 when I pulled the stereo out it was instantly locked

This is nmz787 here, glad people found this work useful! I have had absolutely no issues since modifying my truck, there's no side effects at far as wifi or radio lock out. The wiring is only going to and from the knobs just below the screen, the touch screen input, and the actual screen backlight itself. When I was debugging this, I ended up simply pulling each individual data line one at a time and testing the dimmer until I found the magic wire. One wire disabled the knobs, the next disable the touch screen, and then I stopped after the third one which was for the dimmer override.

Just wondering if anyone has had an issue after this mod. This is the only place I have found that mentions this fix.  I’m about to try it on my 2017.

thanks!

After years of living with the overly bright reverse camera screen that the dealer update did not fix, this mod finally did the trick. One thing to note is that disconnecting the wire also disabled my 110V AC outlet. Small price to pay for no longer being blinded when reversing at night, no other issues and works like a charm!

I'm about to do this, i'll be testing the 110v outlet, if it does shut that off, i'm just going to wire in an on/off switch so I can "connect" it all back to factory when I need the AC outlet (Rare).

Sorry to revive an old thread. Can someone confirm that removing the LAN connection breaks the 120v outlet? 

 

I hate the bright camera but I would equally hate the non working outlet.

 

EDIT: Went ahead and did it. Dimmer function works fine now and the AC outlet still functions without any issue. 


Thanks for this thread.

      OCI, not when but why?

      By Grumpy Bear · Posted

      In the 80's 90's I'd run Honda's 7,500 miles between changes using Red Line HP 5W20 and do it for hundreds of thousands of miles with issues. Back in the day it was an SAE 20 with the HTHS of a SAE 30 and SN add load. It was also very polar. Oxidation VOA was over 120. Besides those motors were SPFI and lean burn tech. I could have likely run it longer but never did.    We had a Toyota bought new I ran on Pennzoil's latest and greatest synthetic of the day with "Penthane". A made up word for a very low dose of PAO. Tried 7,500 mile OCI's in that Group III/VI chemistry and the rings tapped out at 90K. Rocker box wasn't as bad as the one Punch put up but it wasn't good either. Also a SPFI motor.    I'm around 3,750 across the board on these GDI monsters and the oil it tapped out by then usually on TBN/TAN crossover and color. Red Line HP Euro.    The AMSOIL SS brochures tell you to follow the OEM values for the service class but that it can be run up to 25K if monitored. I can't imagine what motor could go that distance and not tap out. I've never owned one.    Yes, I know. Lot's of people do. I'm just not going to be one of them.

      I knew a guy in the early 80's that bought a new Monte Carlo and ran it a 100,000 miles without ever changing the filter or the oil. Just kept adding. It looked like that inside.

      My First Project and GMC has me stumped

      By whenindoubtuseahammer · Posted

      Good evening. I was lucky enough to get passed down to me a 2007 GMC LBZ that was my great uncle's. While the underside and rockers are more or less gone I feel like with time I can restore it to working order since it only has 110,000 miles and he put nearly every option he could get without getting the new body style since he did not trust DEF. So far I have done everything I can think of but when I put the key into the ignition nothing happens. I put 2 brand new batteries in it. Cleaned the terminals. Check all the fuses and relays and they all pass with my multimeter. I know I'm missing something that I just cant think of. The only odd thing is the OBD2 port works which makes me think its not the mega fuse. Any advice would be greatly appreciated.

      Looks nice. I still have my 2000, 1500. Bought a 2025, 1500 for retirement. Feels solid. These trucks have a bad rap on the internet. My brother has a `24 1500, 5.3 with 52,000 miles. No problems at all. Mine hasn`t either but mine`s only at 12,700 miles. Have seen some of these things with 100,000 miles with no problems.

      Howdy! New to the forum of course! My name is Casey, just picked up a 2024 high country midnight edition. First “new” truck in 24 years for me. Driving a 1998 Z71 since 2002. Have been on the GMT400 forum with lots of good info and help there. Nervous about driving these newer trucks and all their electronics…. Did a lot of work on the Z71 myself over the years. New truck is definitely a nice upgrade after 24 years. Photo of the old and new, still keeping the Z71 - has 320,000 miles on her and still running well!
