Installing Brake Controller and 7-Way On 2013 Lincoln MKX

Question:

I have a 2013 Lincoln MKX with no factory tow system. I previously installed a flat 4 plug system on this car but now need a round 7 pin plug for trailer brakes. I will use my existing Prodigy P2 previously set up on another vehicle. I plan to order kit ETBC7 as well as part 7894 plug and wire harness to connect the Prodigy to the car. I have concerns about which color wire in the brake switch harness plug to connect to. Also, what is the best way to attach the 7894 harness wire to that wire in that brake switch harness. Thank you,

The Universal Installation Kit for Trailer Brake Controller part # ETBC7 is just what you need to install a 7-way on a 2013 Lincoln MKX with existing 4-way like the T-Connector Vehicle Wiring Harness part # C56121. There would not be any issues with the Tekonsha Prodigy P2 Trailer Brake Controller part # 90885 either. It should have come with a hardwire harness but if you no longer have this the Pigtail Wiring Harness for Tekonsha and Draw-Tite Brake Controllers part # 7894 will work.

In regards to installing the hardwire harness, the red wire will go to the wire on the brake pedal which is only hot while the pedal is depressed. It should be a purple/white wire but be sure to test these wires yourself with a circuit tester.
