ALL OUR TRAILERS UTILIZE THE 7 PIN ROUND TYPE OF ELECTRICAL CONNECTION   You may choose to RENT one of our CURT Bluetooth Brake Controllers for an additional fee in lieu of permanately installing a brake controller on your vehicle 7 Way RV Connector Pictured above & below is the Pollak (also known as the Bargman) 7 way trailer connector. This connector style is most commonly use on RV trailers and is also popular on horse and utility trailers. This connector is also manufactured by Bargman Company and there are also some generics around. They are supposed to be interchangeable. Wiring color code is maintained among the various brands. Per the illustration below the back side of the connector body is labeled at each terminal with the function assigned to that pin. On the tow vehicle side, pickups and SUV’s with factory installed trailer wiring, wire color alone should not be relied on. Always test and match the function to the appropriate terminal. On the trailer side RV’s for the most part are wired to match the connector colors. It should be noted below that the center terminal is labeled as an auxiliary circuit. Most commonly used for backup lights not a ground terminal as many try to make it. Also after the connector diagrams find more information on wire colors used by GM, Ford, and Dodge.

Trailer Brake Wireing

Wiring Diagram for Typical Brake Control Installation

Four wire connections are required for installation of a brake controller.

1. 1. Trailer feed (usually blue): This wire connects the brake controller to the 6-way or 7-way trailer connector at the back of the tow vehicle. Some vehicles with factory tow packages already have a wire for this connection. If your vehicle isn’t prewired. Run a wire from the brake connector location, under the vehicle, through the firewall, and to the brake controller. Most vehicles already have a pre-existing hole or grommet to get through the firewall. Furthermore, if your vehicle doesn’t have a pre-existing hole, you will have to drill.

1. 1. Ground (usually white): This wire is connected from the brake controller to any reliable ground location.

1. 1. Brake switch (usually red): This wire can be found at the switch at the top of the brake pedal. Usually more than 1 wire runs out from the switch, therefore you will have to test them to determine which wire has power when the brake pedal is depressed. Use a quick-splice connector to tap into this wire.

1. Battery power (usually black): This wire connects power from your tow vehicle’s battery to the brake controller. Vehicles with a factory tow package already have this wire run from under the dash to the battery. Hence a wire must be run through the firewall and connected directly to the battery with an in-line circuit breaker.
