The 2010 Ford Expedition should have a round connector at the rear of the vehicle where your 4 pin plug is plugged in. If there is a round connector there you can use the Replacement Multi-Tow 7-Way and 4 Pole Trailer Connector, item # 74682, to replace the 4-Way OEM connector on your Expedition.

If your Expedition does not have the mating round connector under the rear of the vehicle you will need to use a 4-Way to 7-Way adapter like item # 37185, to provide a 7-Way connector at the rear of the vehicle. Extra wiring will be required to connect the 12 volt power wire, trailer brake wire and the reverse light wire on vehicles without the round factory connector installed.

If you are planning on installing a brake controller the Brake Controller Installation Kit, item # ETBC7, contains the connector and all of the parts needed to do a complete professional looking install. I have included a link to instructions for you to review.

If you have the factory connector and want to install a brake controller you would need a brake controller like the P2, item # 90885, along with a wiring harness for under dash connection, item # 3035-P.
