Trailer Wiring Harness
Your vehicle may be equipped with the seven-wire trailer
towing harness. This harness has a seven-pin universal
heavy-duty trailer connector that is attached to a bracket
on the hitch platform. The seven-wire harness contains
the following trailer circuits:
•
Yellow: Left Stop/Turn Signal
•
Dark Green: Right Stop/Turn Signal
•
Brown: Running Lamps
•
White: Ground
•
Light Green: Back-up Lamps

If you need to tow a light-duty trailer with a standard
four-way round pin connector, an adapter connector is
available from your dealer.
Your vehicle may also be equipped with wiring for an
electric trailer brake controller. These wires are located
inside the vehicle on the driver’s side under the
instrument panel. These wires should be connected to
an electric trailer brake controller by your dealer or
a qualified service center.
