If your tow vehicle is equipped with a five-wire, four-connector harness, it will be necessary
to retrofit the vehicle with the proper connector. Alternatively, the five-wire four-connector
tow vehicle harness can be used with the six-wire five-connector harness. If the trailer is
equipped with disc brakes, the exposed terminal must be wired to the reverse light circuit
of the tow vehicle for proper brake operation while backing the rig.
Attaching the trailer electrical system to the tow
vehicle
Your trailer is equipped with a six-wire, five-connector wiring harness. The colors
function as follows:
White – ground
Brown (2) – taillights, sidemarker lights, and clearance lights for each side of the
trailer
Yellow – left turn and stop light
Green – right turn and stop light
Blue – disc brake free-backing solenoid, to be wired into tow vehicle back up
lights
The above wires each correspond with individual circuits on the tow vehicle. Refer to
your dealer, hitch installer, or local automotive repair shop to have the proper vehicle
connector installed.
