asked by: Chris J
the wire bundle you are looking for looks like the one in the FAQ article I have linked for you. It is located under the left side of the instrument panel to the left of the steering column. The wiring colors should be as follows:
Red/black wire = 12 volt power
White = ground
Light blue/white = input from brake switch
Dark blue = output to trailer brakes
Orange = not used
There also may be some connections that you will need to make under the hood to make everything fully functional. This information is also in the FAQ I have linked.
