7 Pin wire harness?

7 Pin wire harness?
I just purchased an 08 H3 Alpha, but I did not get the Trailering package. I want to get a hitch, and after searching, I found the Trailer hitch FAQ. It talks about the 4 Pin plug, but not the 7. I may tow a few things that require the 7 pin. Is there an adapter or way to have a 7 pin connector with the aftermarket hitch? Any help would be greatly appreciated!
P.S. LOVE the Hummer!!!!!!

an adapter will not give you a true, functioning 7pin -- since a true 7pin has trailer brake power. If you want to add a true 7pin after the fact, you have to get a little box for the trailer brakes in the front, as well as a power line to go from the front of the truck to the back, as one isn't standard if you don't get the hitch. It's a pain, I know..
