Information on Brake Controller Wiring on a 2005 Jeep Liberty

Expert Reply:

Which connector does your vehicle have on the rear bumper? If it's the 4 pole flat connector, you'll need the Brake Controller 7 & 4 Way Installation Kit - 10 Gauge, part # ETBC7, hardwired brake controller installation kit.

We have an FAQ brake page that I attached in a link below that will explain the installation procedure.

Your 4 pole connector will plug into the 7 way connector included in the kit, and you will run a brake wire up to the cab for the controller, as well as a 12V feed to the battery via a 40 amp circuit breaker included in the kit.

When installing the controller, the red wire would attach to the cold side of the brake stop light switch. The blue wire would attach to the brake wire that has been run up from the connector. The white wire would be grounded to the negative battery pole, and the black wire would attach to a 12V power source via the 20 amp circuit breaker included in the install kit.

I attached a link to an installation page below that explains how to wire a vehicle for a brake controller from scratch that you might find informative below.
