As I have done for my last several vehicles, I hardwired my UNIDEN R7 into my BW. Pulling the plastic cover off of the mirror was the actually the harder part. Wiretap BLACK to BLACK and WHITE PIN, Wiretap RED to PURPLE and GRAY PIN. Here are some pics for you.This install has been the same for me on my GM vehicles. The Radar detector only receives power when the vehicle is ON, not ACCESSORY , or OFF.
