Can the 3021-P Brake Controller Harness be Hardwired to the Factory harness on 2010 Ram

Question:

I have the 3021-P which connects my Tekonsha controller to the truck harness. The previous owner cut off the connection plug that comes factory in the harness. Can I get a replacement?

So if I understand correctly you need the vehicle side that mates harness # 3021-P is that correct? If so that is something you will have to get from a Ram dealer. Or you will have to cut off the end that plugs into the truck on the 3021-P harness and wire it up to the vehicle side harness by function.

The brake controller wiring uses the white wire for ground, black for 12 volt power, red for input from the brake switch, and blue for output to the trailer brakes.

Your Ram harness may have the following colors and functions:

White with Red Tracer for 12 Volt Power
Blue with White Tracer for Brake Switch
Green with Black Tracer for Ground
Blue for Trailer Brakes

or it could be this:

Red with Black Tracer for 12 Volt Power
White with Tan Tracer for Brake Switch
Black for Ground
Blue for Trailer Brakes
