The included wiring harness features a male composite video RCA connector that plugs into your aftemarket radio's composite video camera input. You aftermarket radio must be equipped with a composite video camera input and built-in video screen. The included harness also has a reverse wire (purple/white) that connects to the reverse wire of your aftemarket radio's harness for automatic rearview switching when your vehicle is put into reverse gear.

The steering wheel control output consists of a right-angle 3.5mm connector and a light blue/yellow wire (use the connection that your aftermarket head unit is outfitted with). The SWRSU-38C interface module will work with any of the listed aftermarket head units, by setting its 8 dip-switches (see owner's manual for appropriate setting).
