Do you have a mirror that has switched power supplied to it for features like auto-dimming, map lights, compass/temperature, or On-Star? If so, my cord may just be the solution for you!
If your mirror has these features, chances are the mirror has a wiring harness connected into the back of the mirror housing. My little contraption allows you to quickly connect my power cord right into the harness without any splicing or cutting any wires! You simply push the connectors into the back of the wiring harness to tap in to the proper +12v/ground wires. It is basically a 1 minute install!!!
