I just used bits and pieces of the wiring harness, if you get alternative off road's hood mount bracket and light cannon kit you get everything you need and more, for the raptor you have to wire the under dash AUX switch wires and then wire the cannon connectors to the under hood wires and the grounds to the bolt in chassis grounds under the hood, I put my cannons on aux 4 since they barely pull any amps
