So I'm trying to wire this aftermarket head unit up, and I have everything figured out and wired except for the ACC wire. I tried wiring it in with the ignition wire and it just caused problems. Also my cigarette lighters are always on so those aren't an option. Does anyone else have any ideas of how to wire it? Also there's four wires unused wires on the stock wiring harness that I just can't figure out what they are, so I don't know if that has something to do with it. Please and thank you for your help.

 

look in the how to section under electrical or audio I don't remember which one. ACC wire you can run to the sunroof fuse on the passenger side. That's the most common one you will see everyone using on here.
