Parts compatibility question I'm piecing together my motor for the upcomming swap. I started with an L92 out of a 2008 hummer. I've got a E38 computer (needs to be flashed) with the hummer engine harness but havent picked up the DBW peddle or TAC yet. I picked up a complete 2009 corvette intake assembly with injectors, fuel rail, map and throttle body. The intake bolted up nicely and the injectors and throttle body plugged right in. The map sensors are different (both the plugs and the way they mount).
There have been a few posts recently regarding TAC, Electronic Peddles and Throttle bodies lately so I wanted to make sure I'm not backing myself into a corner with parts compatibility.
So I have 4 questions:
1. Can I go ahead and sell the L92 (truck style) intake or are there any parts on it that I might need? IE: are the '09 corvette injectors or throttle body going to cause me any sort of unknow compatiblity problem down the road?
2. Should I sell the intake as an assembly or do you think I can get more for it in pieces?
2. What does TAC stand for?
3. What donor vehicles can I pick up the TAC/harness/Peddle from?

an '08 engine with an E38 ECU wont use a TAC (Throttle Actuator Control) module
The Gen IV engines have the throttle body motor controls built in to the ECU. The Pedal is wired directly to the engine computer, as is the throttle body wiring.
