2019 GMC 2500 reverse wire location

massbowtie · 2022-11-16T17:56:03+0000

I'm looking for the location of a wire for reverse lights on my 2019 gmc 2500 HD. I know I can tie into the tail light. I want to locate it in the junction block to the left of the brake pedal I also know about gm upfitter and haven't been able to figure it out. I need it so I can hook up to a 3 postion switch to be able to turn it on with reverse or constant on. Thank you in advance.

  OK, that really helps. My 6.5’ bed HC sticker says 1,359 lbs., didnt see that small print. Subtract me and some stuff, gives me about 1150lbs. So based on Google for hardwood (1500-2000 lbs), I’m making 2 trips for the 1/2 cord. Problem solved, thanks.

  I went to Home Depot last week and experienced an upgrade push. Unfortunately, since then the Auto start/stop no longer works which frankly is no great loss. However the loss of the front bumper sensors has me concerned, as I had other computer problems a month ago with the fuel gauge and cruise control failing completely. Had to take it to a a dealer in NC for repairs.

  I had the same problem on my 26 Canyon. I went into the setting page and toggled the speed limit indicator into the on position. There was no need for Waze or Google Maps. The speed limit no shows in the HUD as well as on the dash. Hope this helps.
