To add a 4-Way and 7-Way connector for a 2014 Lincoln MKX you will need two separate wiring harnesses because they don't make just one that will add a 7-way connector.

The first harness you will need is the T-Connector Vehicle Wiring Harness item # C56121. This custom fit harness plugs in behind the driver side tail lights. It will provide you with a 4-way connector.

The second harness you will need is the Universal Installation Kit for Trailer Brake Controller item # ETBC7. The kit includes a pre-wired 7- and 4-way trailer connector that mounts easily at the rear of your Lincoln with an included bracket. This kit is designed for use on a vehicle with an existing 4-way flat trailer connector and plugs directly into it.

You will then connect the blue wire to the blue wire on the brake controller, connect the black wire to the positive post on the vehicle's battery, the white wire to ground, and the yellow wire to vehicle's reverse circuit if applicable. This will provide you with the ability to control your trailer's brakes and also provide you with a 12v power wire for you trailer's accessory lights.
