The Baja Designs Upfitter Wiring Harness has been designed specifically for vehicles with factory up-fitter / uplifter switches. This harness simplifies installation of all of our Baja Designs lights. It can also be used to integrate switch panels such as sPOD or other switch panel units. If you plan on using two lights on a single harness, you'll also need our 3-pin OnX6/S8/XL 2-light splitter?PN:613608.
