Find a suitable screw or bolt on the metal chassis of the

away paint as needed for a good connection. If possible,
check the ground connection with a multi-meter. (It should
be at most a couple of ohms.) An alternative source for
ground is the cigarette lighter. (This can also be an alternative
source of +12V power for some applications as well.)
Some models and years may vary slightly in wire colors. If possible, confirm
