Match wires below to the matching function of each wire on your receiver (refer to instructions supplied with receiver). The wire colors of your
new receiver may, or may not, match the wire colors of the adaptor. Match adaptor and receiver wires by function, disregarding color.
Some wire functions depend upon what vehicle the harness is being applied to. See the chart on the next page as a guide for your particular
vehicle before making any connections.
Individually tape off any unused wires.
Refer to the chart on page 3 for the amplifier location in your vehicle, and make final wiring connections following instructions on page 4.
