I have been looking at hard wiring a Uniden R3 into my 19 SS1LE using the GEN 5 DIY radar harness. But looking at the picture I have a different mirror. My Onstar and emergency buttons are in the trim overhead, and my rearview mirror is a basic manual dimming mirror. In the picture on the website the Onstar and emergency buttons are in the mirror itself. I am just wondering where I would plug the harness into? Will I have to pull the overhead trim out and plug it in there?
