Factory Tow/Trailer Wiring Issue

[TopWrightUSMC]

Okay, with key on and hazards on I have 12v at F36 and F37. Nothing at F107/F109. Is it possible the BCM the culprit? 12v on 7 pin connector is good. This doesnt need to be programmed at factory does it? I have the factory installed tow package.

Okay, I appreciate all of the help in troubleshooting this issue. I worked on it from 1500 today and finally have it fixed at 2230. I have checked fuses and tore the passenger side of my JLUR apart chasing the wiring harness to the front of the Jeep. Could not find anything disconnected or broken.

I studied the fuse path and see where the 12v passes straight back to the 7pin connector. The other stop/turn signals pass to the connector also but they also get signals from the BCM. So....I know my Tazer JL bypasses the BCM for several things so I unmarried that rascal and plugged the 2 connectors back into the BCM and IBD if that didnt fix my trailer lights.

I need to read up on the Tazer and see if I need to activate anything in there to activate my trailer tow connectors.

Again, thank you for the responses in helping me try and fix this issue.
