You could just run your ground and acc from your 12v power outlet or you could run them from your interior fuse box, whatever is easier for you. 30 minute job.ok, I've search the site very well but have not found an answer to my question so if I missed it, please direct me to the correct link. I have a homelink mirror I would like to install but do not have the sunroof. Can anybody tell me a good place to tap for switched power? Maybe a description or picture of the wire? I would like to have the homelink work only when the acc is on.
