How to Install a Trailer Brake Controller

Installing a trailer brake controller can help you have a safer ride while you’re out and about in Myrtle Beach.

Trailer brakes are seen in several trailers and are a necessary precautionary measure for slowing down and putting a trailer to a halt. Before you start with your installation of a trailer brake controller, keep the following tools handy: a trailer connector, a nipper, screws and a screwdriver, a brake controller.

Here’s your guide on how to install a trailer brake controller.

Choosing the Right Controler

Time-delayed controllers are suitable for occasional towing with light-weight trailer and cargo and need manual synchronization. Proportional controllers, by contrast, get synchronized automatically and are best suited for heavy tows and weighty cargo.

Installing the Trailer Connector

• Choose an appropriate place to install it - the bumper near the wire connector is a good option.

• Remove the core and white sleeve after removing the set screw.

• Insert the wire connector through the trailer connector and cut the wire sheathing to find 7 wires within.

• Strip their insulation and connect each colored wire with the set screw.

• Screw down the set screw once wires are attached and re-install the white sleeve.

Installing the brake controller

• Choose an appropriate place to install it - under the steering to the right side of the driver is a good option.

• Drill 2 holes in the place identified and install the brake controller’s bracket.

• Select a spot underneath the mounted brake controller to run the wires.

Wiring the brake with the controller

Connect your brake’s junction box with the controller through 4 cables:   

• The white cable – connected to any metal part under the steering wheel.

• The blue wire - the trailer brake cable – connects the trailer connector with the rear of the vehicle.

• The black cable – operates the battery because it’s a 12-volt wire.

• Red wire (signal cable) – displays the number on the brake controller screen.

Wiring the Brake Controller and Trailer Connector

• Connect the trailer connector’s bracket with your car’s rear-end.

• Plug the 7-way trailer connector to the bracket and run the blue wire to the car’s rear end trailer connector.

Testing the trailer brake controller is the final step in its installation.
