cheers for the suggestions, i tried that gm upfitter but don't understand how to find what i need. and with all data i actually haven't got the engine. i need the diagrams to work out if i can use the engine in a conversion due to being gmlan and not can bus. so dont want to subscribe for something i may not use if i have to go lbz

I gathered you were doing a conversion. What are you putting it in?

If you're swapping in the ECM, TCM, column, and cluster, you should have no problem making all those things work.

Merged your two threads b/c they are on the same topic.

As for Upfitter, from their first page:

Click "Body Builder Manuals" on top menu
Click "View Light Duty"
Click "Light Duty Prior to 2013" from the dropdown menu
Click "Light Duty 2008" or "Light Duty 2009"
Click the PDF file with the header "Electrical -- Pickups and Chassis Cabs" about 9 items down in either year.
Open downloaded PDF file.
Search for what you want.
:)
