2017+ Reverse Camera Dimmer Fix

ASC43 · April 7, 2019

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.

I’m really interested in trying this on my 17 Silverado but Does this disable the WIFI? I use it often.

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).
