The wire colours for a standard 7-pin for each pin are on-line (Google), but the joke is in the wire colours GM uses for the pins. Different! You have to wire the trailer 7-pin the standard way, not the GM way.
If you ever have to change the GM 7-pin on the back of the truck to a standard one, it gets complicated :) BTDT.
Don't get mixed up with the mirror image problem for each side of the connection.
