My mom is a recent cancer survivor and my father and I have decided to get off our asses and build her dream truck (66 Chevy SWB)

I have:

2004 LS1/LS1 Motor out of 2004 Corvette
4L60E out of 2004 Silverado
CTS-V Gas pedal
Ls2 90mm 4 bolt throttle body
411 PCM


I have the C5 Corvette TAC module SOMEWHERE but I cannot find it at the moment.

What all combo TAC Mod/LS2 TB combo can we run? If I have to buy a new gas pedal and TAC module I will. I know I am about 10 years late on the LS game but I haven't been able to afford it and still can't! Haha

Anyone? I see a lot of people discussing it when I Google but no real definitive answers in regards to a setup

Who are you getting the harness from? What tune is going into the PCM? Just because the motor came from an 04 'Vette does not mean the TAC and APP from the same car will work because the tune may be a different year. Best bet is to get the harness, tune, TAC and APP from the same source such as PSI.

Probably PSI at this point. I'm asking because if I cannot find my TAC in storage and figure out the working combo I am going to trash the DBW idea and go with DBC since I cannot afford to buy another TAC/Pedal setup

I can help you out. I have done this to a few custom harnesses for a LSA blower conversion. PM if interested. I can get a pedal and TAC module for 150$ that works with the GTO throttle body

Well! I found my C5 Vette TAC module and my 411 PCM finally. Is there a way to make this work with the LS2 TB?

Im not 100% sure but I don't think the LS2 TB will work with any 411 PCM. The LS2 TB came out wit the E67 ECM which did not require a TAC module.

Not true, the silver blade 90mm from the early ls2 and ls7 applications is compatabile with the corvette tac. C5 owners use them for 90mm conversions.
The gold blade 90mm from the later ls3s and ls7s rotates in the opposite direction and does not work the the corvette tac.

A quick Google search will turn up a $50 plug and play harness for the swap.
