Without buying a separate ignition harness splitter, you'll have to splice into your factory ignition harness. I HIGHLY recommend spending the 10-15 dollars on the splitter. In addition to the splitter, you'll have to run a couple wires which include the parking brake sensor. Otherwise a fairly straight forward install. There's a how-to floating out there somewhere. I think I used the one on scoobymods.
