What are the Wire Colors and Functions of the Nissan Factory Brake Controller Harness


Have an older Voyager to install in a 2011 Frontier. What is the color matches from the voyager to the Nissan jumper cable?


Expert Reply:

From what we have found, the Nissan factory brake controller harness has the following color/functions:

Nissan Red to brake controller black for 12-volt power
Nissan Red with green tracer to controller red for input from stoplight
Nissan black to controller white for ground
Nissan brown with white tracer to brake controller blue for out to trailer brakes

If there is a red wire with blue tracer it is not used by the brake controller.

You will want to use a circuit tester like # PTW2993 to test the Nissan harness to be sure of the functions.
