I personally own a C6 but my brother has an '03 Stang and we both inst. D3's. From the Corvette Forum I figured out how to hook up my illumation wire. It went to a grey wire on a button that changes brightness when the lights dim. (It was a grey wire) Anyways I've been searching trying to figure out where I should hook his up and some people have said that it is a grey wire on the Stang but I just wanted to see if anyone has any experience with Stangs and what we should be hooking it up to.
