Do you mean cable?

yes-- drive by cable-- -- i didnt get the gas pedal for the LS2 with it so i am not sure if im better to find a drive by wire gas pedal and corresponding wiring harness or convert to cable /lokar.

What ecu are you running. Newer ones dont have IAC capability.

i need to buy a computer as well --
i was supposed to get the wiring harness and ecu but the wrecker sold that separate from motor.

Bbk makes a 90 mm cable tb with the correct 4 bolt pattern.
As far as your wiring problem, you can get a computer and a harness out of a 4th gen ls1 vehicle that will run the cable tb. Just have to get the 58x to 24x converter box and everything should plug n play.

As pointed out, if you have a 58x motor, I'm not sure if there are ecus that support iac. If you start adding up converters etc, it might be cheaper/easier to get the correct harness, ecu, pedal for your motor.

Any of the 4 bolt cable aftermarket throttle bodies should work. I run a FAST 92MM on my stock ported LS2 manifold. No adapter or spacer. You are going to need a Gen3 PCM with IAC drivers and code to run them though, and a throttle cable bracket. I use the 411 PCM out of the 4th Gen Camaro T/A.

Agree with much above. If you have a 24X engine, you wont need a converter just a 411 PCM and a harness with provisions for knock sensors mounted on either side of the engine and a front mounted Cam sensor. If you have a 58X engine, you will need the same plus a Lingenfelter converter box. We can help you with all these items. Give us a call if you like.
