How to Wire in a Brake Controller in a Dodge Ram


A brake controller is an electronic device mounted in your Dodge Ram’s cab that receives a signal from the brake light switch whenever you apply your foot to the brakes. It then sends a signal out through the trailer wiring coupler to engage the trailer’s electric brakes. Most brake controllers are adjustable to allow the driver to determine how much braking force is applied.

Wiring a Brake Controller in a Dodge Ram

Step 1: Disconnect the ground cable from the negative battery terminal.

Step 2: Separate the brake controller from the mounting bracket.

Step 3: Use the supplied self-drilling self-tapping screws to mount the bracket to the lower trim panel underneath the steering column. Make sure it is in a location that will not interfere with the proper operation of the gas, brake or clutch and will not be in the way of entering or exiting the vehicle.
