Auxiliary power connector may vary depending on the car. Check your car’s auxiliary power connector
diagram to make sure the connections match correctly. There are three basic types (illustrated below). You

After matching the connections and switched power supply leads correctly, connect the unit to the car’s
power supply. If you have any questions and problems connecting your unit that are not converted in
