In Reply to: Radar detector - wireing (can't find "ground") posted by YS on February 21, 1999 at 11:58:25:
You found it! The car's body. You should ground to the body of the car when possible. Find a nice place under the dash somewhere and put it under an existing nut or bolt, as you did with the door bolt. If you can't find a good place close, that's OK. Run a length of wire to a suitable place. A radar detector isn't a high current device, so you can use small, easy-to-hide wire.
: I've installed a radar detector yesterday in my new 328i.
: I put it on the left corner of the windshield and run cable in the small opening between the windshield and the interior plate to the right side, then beween to interior plates down to the clove compartment and on the the fuse box.
: I've put one wire under the fuse that controls the cigarette lighter (the wire has a capsule with it's own 3A fuse in it) but I couldn't find a "ground" anywhere close to the glove campartment area. I wound up putting ut under the nut that holds the passenger door.
: Does anybody know where the "ground" is inside the car?
