No power to Trailer Brake Controller anymore. Need help
stewie:
Hi all - it's been a long while since ive been here, but i figured this may be a good place to ask...
I installed a Reese Towpower in my 2012 sierra 1500 back in 2018. worked perfect. Fast forward to this year... the 7 prong Pollack plug in my trailer came lose while towing and i could not figure out why nothing was working when i wired it back up. i finally got everything but the trailer brake functioning. i had to go to the trailer dealer i purchased mine from and ask to see how the MFG wired the plug up. Ok, cool i got it. went home and changed up my wiring.
Now my trailer brake controller under my dash has NO power. I checked all trailer related fuses under the hood, reset the harness, checked the wires and prayed. I cannot figure out why I have no juice going to the TBC. I wonder if me having a misaligned or wrongly connected wire initially caused an issue somewhere?
Any insights will be helpful.

If the controller doesn't have power trace it out. Black wire has battery power always. White wire is ground. Red wire has power when stepping on brakes only.
If you used a gm harness that plugs in under the dash, it will get power from a large fuse.. like 40a. I think it's called "stud #2" or auxiliary iirc
