One harness included. If you're wiring a pair of lights, order two. Note about vehicle year selection: Ford reversed the wires on the fog light plugs in 03, so the only difference in the harnesses is the orientation of the positive and negative wires on the 9005/h10 plug end of the harness. please enter the year of your F-series truck in the additional notes upon checkout so that you will receive the correct wire configuration. If you mistakenly get the wrong one, just swap the wires in the plug. There is a small tab you press down and the wire will come out of the plug. If you need a harness for another application, you can choose either of the two, and just reverse the pins if needed for your application. warning: Your truck will need to have the existing OE fog light circuit installed for this harness to work. The factory fog light wiring has a 10amp fuse in the fuse panel, you will need to make sure your led lightbar draws less than 10 amps. A typical 20" led light bar draws around 6-7 amps, and single led pods are much less.
Works with the following bulb types:
