Wiring a 2012 Lincoln MKT For Flat Towing


I have a 2009 Safari Cheetah motor home and I want to tow my 2012 Lincoln MKT behind it 4 wheels down. I need to know how to wire up my brake, turn and tail lights. Do I need to install a Brite-Light Converter #RM-732 between my motor home and my MKT or not?


Expert Reply:

For wiring your MKT for flat towing, you have a few different options. The simplest option would be a magnetic mount lamp kit like part # RM-2120. The plus for a system like this is that it's very easy to install and remove, although some folks don't care for the exposed wires.

A second option would be a bulb and socket kit like part # RM-155. Installation involves drilling 1 inch diameter holes in the rear of the taillight assemblies, but no splicing into the vehicle wiring in necessary, unlike diode kits.

The third option would be a diode kit like # RM-154, which would tap into the taillight circuits of your MKT. Your MKT has what's referred to as a combined taillight system. The signals for brake lamps and turn signals are combined onto the same circuit. The absence of amber lenses for turn signals in your taillight assemblies confirms that you have a combined taillight system. Most motorhomes also have a combined taillight system. The only instance where you would need the # RM-732 would be if your motorhome had a separate taillight system, with separate amber bulbs for the turn signals.

I'll link you to two wiring diagrams. The first would apply if your motorhome uses a combined system, the second if your motorhome uses a separate taillight system.

I'll link you to some FAQ articles about flat towing that I hope you'll find helpful. According to my research, your MKT is capable of being safely flat towed. You'll want to confirm this for yourself with Lincoln.
