Parts Needed to Install Brake Controller On 2009 Ford Van w/ Factory 4-Pole Trailer Connector


I have a 7 pin that I installed years ago, but I think the OEM plug it came with only provides lights brakes and reverse etc. What would I need to put in a controller and possibly benefit from existing wiring? Having a controller would be great for my camper that has electric brakes.

Given you description, I'm guessing your van was originally equipped with the factory 4-pole trailer connector that provides lighting functions only.

You'll begin by choosing a brake controller. You can't go wrong with the Tekonsha Prodigy P2, part # 90885. You'll also need the # 3034-P brake controller wiring adapter. The adapter plugs in to the connector located behind the small change pocket in the dash, but the brake output circuit is NOT ran to the rear of the vehicle, so you'll need a length of # 10-1-1 wire (sold by the foot) long enough to run from the rear of the brake controller through the firewall, under the van to the 7-way at the rear, where it would wire to the 7-way according to the diagram shown in the FAQ article I've linked for you. At the brake controller, you'll want to sever the blue wire on the 3034-P and connect the other end of the blue wire.

If your trailer needs a 12 volt power feed, you can run one from the 12 volt pin on the 7-way to the positive battery terminal of the battery, running it through a 40 amp circuit breaker like part # 9510. The # 10-1-1 wire would work for this as well.
