If the vehicle is equipped with the
“
Heavy-Duty
Trailering
”
option, please refer to
“
Heavy-Duty Trailer
Wiring Package
”
earlier in this section.
When the camper-wiring harness is ordered without the
heavy-duty trailering package, an eight-wire harness
with a seven-pin connector is located at the rear of the
vehicle and is tied to the vehicle's frame.
Electric Brake Control Wiring
Provisions
These wiring provisions are included with the vehicle as
part of the trailer wiring package. These provisions are
for an electric brake controller. The instrument panel
contains blunt cut wires behind the steering column for
the trailer brake controller. The harness contains the
following wires:
.
Dark Blue: Brake Signal to Trailer Connector
.
Red/Black: Battery
.
Light Blue/White: Brake Switch
.
White: Ground
It should be installed by your dealer or a qualified
service center.
If the vehicle is equipped with an ITBC, the blunt cuts
exist, but are not connected further in the harness. If an
aftermarket trailer brake controller is installed, the ITBC
must be disconnected. Do not power both ITBC and
aftermarket controllers to control the trailer brakes at the
same time.
