How to Convert a 4-pin Flat to a 7-way Plug and Install a Brake Controller on a 2003 Ford Ranger FX4


Hi I have a 2003 ford ranger FX4, 4.0 V6. Standard it has the 4 pin flat connector for trailers. I was wondering is their anyway to convert this to a 7 way connector? I am considering buying a small travel trailer. Also can a electronic brake controller be installed? thank you

Expert Reply:

I recommend using brake controller installation kit # ETBC7 to adapt your 4-pin flat plug to a 7-way connector. This will adapt your 4-way plug to a 7-way, and it will include the circuit breakers, additional wire, and various connectors to install the brake controller and adapter on your 2003 Ford Ranger.

I recommend the Prodigy brake controller # 90185 to equip your vehicle for towing with electric brakes. The # 90185 brake controller includes a pigtail that will allow you to hardwire the brake controller directly to your vehicle.

The 4 brake controller wire functions are:

White: Ground, attached to a clean piece of unpainted metal.
Black: 12v lead, attached to the vehicle's positive battery terminal with a 40amp circuit breaker.
Blue: Electric brakes, attached to the blue electric brake wire on the 6 or 7-way plug.
Red: Stoplight switch, normally located directly off the vehicle's brake pedal.

I have included a link to a video demonstrating how the # ETBC7 kit and # 90185 brake controller would be installed on a similar vehicle, as well as some information on installing a brake controller starting from scratch.
