Hope someone can help.... I need to figure out if the wiring for the non-used "aux or electric brake" wire in the 7 pin tow harness, that is run up and into the front driver side cab area, and where I could find it under the front dash?. Hopefully someone might have a wire bundle to look for and/or a wire tag up front. Thanks for the help!
In the under hood power distribution box fuse 13 (30amp) is "trailer tow electric brake controller feed". Not sure if this is the one you are looking for or helps.
