Did you get the numbered list from CD that told what each wire was, I didn't when I got my harness so they faxed it to me. If not I can look it up for you when I get home tonite as I still have all that stuff.
Also you might find this helpful. it's the wireing diagram that I used when installing my harness.
On my diagram black is ground, Green hooks to Black #16 at the terminal block and Brown hooks to Green #15 at the terminal block.

I'm a visual person so I always have to have a current wiring diagram in my truck in case I have trouble.
