Trail Tail Wiring Diagram. Was for the tail lights i believe. The following wiring diagram and electrical system schematics provide detail.
I need to see how the modulator that controls the turning signals and makes them brake lights as well is. I have noticed that the PO installed a trailer brake extension and he hacked into the wires just inside the tailgate. But got the info I need!

You must determine and verify which wire color goes to which!
If your vehicle is not equipped with a working trailer wiring harness, there are a number of different. So its possible that fuse is dead and yet the turn signals would. I'll just use process of elimination to find which wire is the brake light.
