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/retailer 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.

Auxiliary Battery

The auxiliary battery provision can be used to supply

electrical power to additional equipment that may be

added, such as a slide-in camper. If the vehicle has this

provision, this relay will be located on the drivers side of

the vehicle, next to the underhood electrical center.

Be sure to follow the proper installation instructions

that are included with any electrical equipment that

is installed.

Notice: Leaving electrical equipment on for

extended periods will drain the battery. Always turn

off electrical equipment when not in use and do

not use equipment that exceeds the maximum

amperage rating for the auxiliary battery provision.

Trailer Recommendations

Subtract the hitch loads from the Cargo Weight Rating

(CWR). CWR is the maximum weight of the load

the vehicle can carry. It does not include the weight of

the people inside, but you can ﬁgure about 150 lbs.

(68 kg) for each passenger. The total cargo load must

not be more than the vehicles CWR.

Weigh the vehicle with the trailer attached, so the

GVWR or GAWR are not exceeded. If using a

weight-distributing hitch, weigh the vehicle without the

spring bars in place.

The best performance is obtained by correctly spreading

out the weight of the load and choosing the correct

hitch and trailer brakes.
