I rec'd my V1 radar yesterday and I would like to install it today to the rear view mirror. I need help with grounding. I know what wire I need to tap into for power (red) but I need to know how you guys are grounding. Any help would be appreciated.

 

Don't assume that red is power,use a muti-meter to check for a power source with key on only.you can go through the over head console and find a power and ground for the map light,dome light circuit.make sure it is battery voltage and a good ground.do not use a test light
