I think I figured out your last question... The instructions won't answer this -- because it depends on your car. You need to find the ACC / IGN wire in your car and splice into that wire - then run the spliced wired to the ACC wire on the M2-atx. I don't know anything about your ride, so I would have to do some research to tell you were to look for that particular wire. Google around for a wire diagram for your car as a starting point for find the ACC wire.
