Chevy Astro Trailer Wiring

[jdpok]

Heys Guys (and Girls), I was a member on the old board and just resigned up, haven't posted my profile yet.
I just bought a 2003 Chevy Astro conversion van, now I need to wire it for my PU. I have an '87 Starcraft Nova, with a 7 Pin connector. I just found where the Conversion company buried the trailer wiring and need some help. Here are the wires and colors:
Brown-         RR Lamps
Yellow-         LH Turn
Dk Green-     RH Turn
Lg White-     Ground
Lt Green-      B/U Lamps
Sm White-     HI MT STP LP
Blue-            Aux Circuit
Orange-        Fused Aux

The info above comes from a label attached to the harness. They don't seem to match up to the colors I have seen on a standard 7 pin connector. The Blue is usually for Electric brakes, which I have, but I'm not sure. Not sure what the Small White wire is either. Has anyone wired an Astro before with a similar harness?  I also have a Prodigy Brake controller I need to factor in. Thanks for any help you can give, John

Welcome back.  

Wiring is my weak point  :eyecrazy:  so I can't help you there.  I am sure someone else will be able to help you.  The Prodigy is a great brake controller.
