I bought a silver blade LS2 throttle body from a GTO for my 02 vette. But, the appearance and connectors are different. (2 electrical on vette, 1 on GTO, and the vacuum port is not on the GTO TB. am I missing something or will this not work on my vette? If it will work, what do I need to get to adapt it? Just changed to a new manifold so the obvious 3 bolt vs 4 bolt is already taken care of.

Thanks

You need the ls2 to ls1 throttle body wiring adapter it's around $40, summitt, ebay, ect carry them

I have the wiring adapter. But on the LS2 throttle body there is the drive by wire plug in but on the other side nothing, no TPS, (or what I am guessing is the TPS) or the vacuum ports or water ports as are on the LS1 Throttle body. Thanks

Yes there is just 1 connector on the ls2 TB that connects to one end of the adapter harness and the other 2 connect to the wiring harness, the plugs are different so you should be able to tell what goes where just connect the tb one first then go from there

coolant runs through the ls6 tb you just bypass it and connect lines together, there is no coolant running through the ls2 tb

Great, thank you so much, you just saved me selling this to buy another one just like it lol
