Installing New Trailer Connector to Use Trailer Brake Controller on 1994 Ford F-250

The Curt T-Connector 4-Pole harness you referenced, # C55316, is a correct fit for your 1994 Ford F-250 and plugs in to a factory connector at the rear bumper to provide basic lighting functions for your trailer.

If your truck does not have a factory 7-way trailer connector you will need to have this working 4-pole connector in place to install one for use with a brake controller. You will also need a trailer brake controller, such as the reliable and popular Prodigy P2 # 90885, as well as an electric trailer brake controller install kit, part # ETBC7. This kit includes the 7-way connector and bracket, wiring, circuit breakers, connectors and a circuit tester to verify proper operation.

I have linked a video for this kit as well as a detailed article on brake controller installation that details the process, including photos of the under dash connector where you will plug in your brake controller. The electric brake control harness on your 1994 Ford F-250 will be located under the center dash just below the ash tray. There will be a black tab and the connector for the harness can be found behind that black tab. You will use plug-and-play harness # 3035-P to connect your brake controller to the under-dash port.

If your truck already has the factory installed 7-Way trailer connector, the only part needed to install a brake controller is the brake controller itself and the quick-connect harness, parts # 90885 and 3035-P.

We offer a range of trailer lights that can be seen using the link provided. You can use the filters at the left-hand margin to narrow the results to just those lights that suit your trailer requirements. You can sort by color, shape and bulb type. You will want to use 14-gauge wire to replace or add new wiring on your trailer; we offer part # 10-1-1, sold by the foot.
