: Trying to wire radar detector into mirror - '03 DeVille

01-03-12, 05:30 PM
I want to mount a radar detector and utilize a switched power lead from the mirror harness. The harness connector is a double row of about 18-pins (I didn't count the holes). Just wondering if anyone has done this on a 2003 DeVille and which wires did you use?

Thanks for any help......

No one can help me get a 12 volt switched lead and ground?

Well I don't know your deville but for the switched 12v u can tapp into a fuse line and install a switch on it unless u wanna put a relay on it u can. As for a ground ur mirrors housing should be all plastic so you might want to use ur door behind the panel as a grounding point

Thanks, but I got out my volt meter and found two suitable 12v wires.

All set, thanks
