Are you wanting to install the trailer wiring or do you have the factiry hitch and connector and just need a converter that changes the round 7 pin factory plug to a standard 4 pin plug? If you are just looking for the converter, any place that sells/rents trailers should have them, I got mine from U-Haul when I rented a trailer. If you have the factory 7 pin connector, the pins are marked on the flip up cover as to which pin correspondes whith which lights, and the the wires on the back of the connector go straight through, so whatever position is listed on the flip up cover for the light you're looking for, just look directly behind the connector for the corresponding wire. I don't think the cover lists the wire color, just what it supplies power to. Hope this helps a bit...
