Driving and Operating

If the vehicle is not equipped with a 7-pin
trailer connector, the body harness has
provisions to connect a trailer harness and a
7-pin trailer connector which is available
through your dealer.

Use only a round, seven-wire connector with
flat blade terminals meeting SAE J2863
specifications for proper electrical
connectivity.

The seven-wire harness contains the
following trailer circuits:

Electric Trailer Brake Control Wiring
Provisions

Wiring provisions for an aftermarket electric
trailer brake controller are included with the
vehicle as part of the trailer wiring package.
The harness contains the following circuits:

Electric Trailer

Battery Feed

Red/Green or

White/Blue

Ground

Refer to the aftermarket electric trailer brake
controller owner's manual to determine wire
color coding of the electric trailer brake
controller. The wire colors on the brake
controller may be different from the vehicle.
The electric trailer brake controller should be
installed by your dealer or a qualified
service center.

If equipped, there are four blunt cut wires
inside the front driver side instrument panel.
It will be necessary to have a technician
connect the 12-volt power to the engine
compartment fuse block.

Trailer Lamps

Always check all trailer lamps are working at
the beginning of each trip, and periodically
on longer trips.

Turn Signals When Towing a Trailer

When properly connected, the trailer turn
signals will illuminate to indicate the vehicle
is turning, changing lanes, or stopping.
When towing a trailer, the arrows on the
instrument cluster will illuminate even if the
trailer is not properly connected or the bulbs
are burned out.
