5.3 Install?

Anybody have a 2005 or close 5.3 with DBW throttlebody they can look at their TAC module connector C2 and show me a pinout for it. All my pinout and wiring schematics show only 6 wires used, and mine has 9 wires. 3 extra wires are Dark green, gray and yellow/ black, I'm pretty sure. I'll have to get a pic today. I'm this close to getting it running. Next time I unpin a plug to pull wires through firewall I'll draw a pinout for the plug. I thought it would show all wires in my drawings and schematics. Wrong. This is the harness from the pedal to the TAC module. Thanks.

Re: 5.3 Install?

take a look at this thread I made awhile ago.

There are 3 wires that go to the cruise control switch, are these the three?

Re: 5.3 Install?

Hey, thanks for all the quick responces. I just found the above schematic myself as well on LS1 tech search. Had to read a few threads, but finally found. Again thanks. Hopefully have this pig back together and running today so can go get exhaust hooked up and go to the Petty Jean Arkansas swap meet with it. Thanks again.
