About all I can offer you is factory wiring schematics for the vehicle system, you will have to determine from there. I would recommend an installer do the job, you could create more problems and not know it was a result, like excessive battery drain. Let me know if you would like the schematics, and give me some option(RPO) codes, for example UQ4, UIL, or UIR. I believe your RPO sticker should be under your spare tire cover.
