Recommended Trailer Wiring Harness With 4-Way And 7-Way Connector For 2014 Ford Explorer


For my 2014 Ford Explorer I would like to purchase the Pollak 7- and 4-Pole Trailer Connector Socket w/ Mounting Bracket - Vehicle End Code: HM40975. Now I would like to be able to tow a trailer with either the 7- or 4-pole plug. Which wiring harness would allow me to do that? Would I simply plug in a 7-pole connector to this connector socket and both the 7- and 4-pole plugs will work? I will need either one at any one time so I need them both to work. Thanks

If you have no trailer connector on your Explorer there are a couple things you will need to get a functioning 4-way and 7-way connector.

First you will need to install a 4-way wiring harness like part # 118540. This is a simple installation. You just plug it into the wiring harness on your Explorer that is located under the rear of your vehicle on the passenger side.

You will then need part # ETBC7. This plugs into the 4-way connector and then you will need to install the remaining wires if needed. Typically, a 7-way is used when you have brakes on a trailer and need to send the signal from the towing vehicle to the trailer brakes. I have attached a drawing that shows how the wiring is normally run when installing a brake controller and an # ETBC7. The # ETBC7 has a 4-way and a 7-way trailer connector that are active when installed. any wires from the # ETBC7 that are not being used can be capped and secured out of the way.

If you need a brake controller I recommend part # 90885. This is our most popular brake controller because it is easy to install and operate.

When working with electrical connectors I recommend using dielectric grease like part # 11755. This keeps dirt and moisture out of the electrical connections and helps prevent corrosion.
