Nissan Frontier factory wiring mixed up
« on: December 06, 2021, 09:10:50 PM »
Installed OEM towing wiring kit for Nissan Frontier 2019 truck, and Redarc Tow-Pro Liberty Brake Controller - Proportional Plug-and-Play Wiring Harness for Redarc Tow-Pro Trailer Brake Controllers

All went well, I thought. Never had it hooked to a trailer as I did not have one with brakes.
Found a trailer in NH. Good little drive for me. Anyway, decided to buy and bring it home. Checked it over, aired up tires hooked up wiring, trailer brakes come on but will not turn off till pigtail is unplugged from truck.

Checked with RV dealer about it a tech said Nissan has had a wiring mix up front under dash to do with tow wiring. I checked it out at the 7 way connection found blue and black wires working in reverse. One is for brakes, one is for 12V to battery. Pulled the two pins out the back of 7 way and reversed them. All is well... A unknown % from a few years are like this. Just a FYI
