I have been searching trying to find a good spot to connect to a switched 12 wire. I am hardwiring my radar detector and need a ground and switched 12 volt wire. I am going to splice into the 12 volt wire and then the ground lets me screw it down. I have about 4 feet of wire I think. Can anyone help me find a switched 12 volt wire and a place so I can screw down the ground? Thanks.
