I installed this on our 2012 Fiesta. It's also good for
Lincoln MKS. I made sure not to cut any of the wires, so they are all full
length. This harness is in perfect condition, with its original installation
Provides a 4-way flat trailer connector at the back of your Ford Fiesta to power your trailer's signal lights Connects quickly and easily Locate connection points in trunk Plug in connector Run hot lead to car battery Powered module connects directly to battery to avoid overloading vehicle's electrical system Constructed of 16-gauge bonded wire Comes with dust cap for 4-way flat connector Specs: Maximum amperage: Stop/turn lights: 2.1 amps per circuit Tail lights: 5.6 amps per circuit Installation This custom-fit connector plugs into your Ford Fiesta's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse. Once installation is complete, the 4-way flat connector will be stowed within your trunk. It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
