check and see if your truck is pre-wired, most (if not all of them) are.

just glance under the front bumper and see if you see the wires zip-tied under there.

you will need a switch (can purchase the OEM one for like $100, or an aftermarket for prob $5)

and also a relay (can purchase one from the dealership for like $70, or one from autozone for like $20 .. part # 41-5154 at autozone)


hope this helps
