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.
Your receiver illumination wire could be Orange or Orange/White. As with other wires, match this wire to illumination wire in this harness by
function, not by color. If your receiver does not have an illumination wire, tape off the illumination wire.
Individually tape off any unused wires.
Make final wiring connections following instructions on the next page.

run wire directly to the battery or an appropriate fuse.
