WIRING CONNECTIONS

Make sure you have good chassis ground. A good ground connection will eliminate most
electrical noise problems. A good chassis ground requires a tight connection to the vehicle‟s
metal chassis. The area around the ground connection should be clean, bare metal without rust,
paint, plastic, dust, or dirt for a good electrical connection.

of the wiring!!!
For some car models you may need to
