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.
Caution:
Do not interchange the connection of the wiring!!!
For some car models you may need to modify wiring of the supplied power cord. Contact your
authorized car dealer before installing this unit.
