How to Convert the 7-Way RV Connector on a Ford Truck For Towing a Trailer with 4-Way Flat Wiring

Question:

Could you tell me how to change my 7way blade wiring to 4 wire so I can tow my 4wire flat trailer? Thank-you My Ford truck has the 7way

Expert Reply:

You have two options for towing your trailer with a 4-Way flat connector.

The easiest option is to use an adapter that allows you to plug the 4-Way connector into it and then plug the adapter into the 7-Way RV style trailer connector on your truck. The Pollak 7 Pole to 4 Pole Connector Adapter, # PK12716, would work great for this application.

The second option would be to use a 4-Way Hardwire Kit, # 18252, and hard wire a 4-Way connector under the vehicle. Use the included circuit tester to probe the wiring coming from the back of the factory 7-Way and connect the appropriate wires to the left and right stop and turn signal circuits and the taillight circuit. We have a video showing this type of installation, the vehicle is different but the wiring principle is the same. You will be able to access the circuits for your tow package under the center of the vehicle without removing the taillights making the install a bit easier.
