"Standard" Wire colors to the controller (Tekonsha and others):
- Black, Battery Positive to controller
- White, Negative Ground for Controller
- Blue, Brake feed from controller to Trailer plug at back of truck
- Red, tap into truck Brake light switch signal to tell controller to apply brakes
Remember, the above colors are just a GUIDE. your colors may be different, read the instructions!
We found a easy spot on the firewall and grounded the ground wire under the dash with a sheet metal screw.
We tapped into the WHITE wire with the Green tracer for the brake light signal (to the red wire on the controller) Test to be sure, it must power on when the brake pedal is pushed. Your color may be different!
Battery feed was taken from the battery (under the hood)
The Ground wire (white) was grounded under the dash
We used red jacketed 2 conductor wire for the brake wire and power feed. One wire feeds power to the controller, and to the back of the truck. The yellow block wire connector is a HD "Scotch Lock" side tap connector. One wire (white wire in this picture) is the brake power from the controller to the back of the truck.
The instructions that come with the converter are pretty easy to understand, and hooking up the tail light wires was very simple. Using a 10mm socket, we took out both tail lights, plugged in the converter to each side, and hooked the power to the converter. Done! All wires passed down under the truck and were run outside, so you do not even pull any panels out of the inside!
