I looked at all the other threads and everybody seems to be hooking them up under the dome lights. I wanted to run the wires of the radar detector to the A-pillar on the passenger side and splice it in there. I figure from the earlier discussions that the blue wire is the Hot wire (always on) and the red wire is also the hot wire but is on only when the ignition key is turned on. The black wire is ground right? So will I find the red and the black wire in the Passenger side a-pillar? I want the radar detector on only when I turn the engine on.
Also I have a bell detector and it has a power jack. I am guessing I can just cut the power jack away and use either one of the wires for ground and the other for +ve
