swapped a 5.3 with a Holley TerminatorX into my 89 IROC. got the cruise control cable hooked up to the throttle body, but can anyone tell me what wires to hook up to what to get the cruise working again?
it's a really nice thing to have on long interstate jaunts..

 

so no one has gotten the factory cruise control to work as a standalone setup?

 

The Holley Terminator does not support Cruise Control. Dakota Digital has a stand-alone system for adapting CC. I used an E38 ECU, reprogrammed to the SSR configuration for CC with a manual transmission and using the GM stalk controls.

 

Well, I'm unsure I fully understand, but I'll throw this info your way. I swapped in a 350 and removed the computer, which grounds the CC. A reground did the trick. If that's the least bit helpful, the following link shows what I did:

That is awesome, thanks for sharing. I want to get mine working now that I know I can keep it.

 

Glad to help.

i want to use the factory cruise control as a standalone.
looks like one other guy already answered the question.

 

at is exactly what i was looking for. thanks.
that will cross off one more thing on my list to make the car as functional as it was with the stock TPI 350..
next up is the AC..

 

finally got this done today.
simply grounded the black wire with a white stripe in the plug down by where the ecm was and the cruise works perfectly now.

 

I'm glad all went well.

it was such a simple thing to do and should have been obvious to me from looking at the wiring diagram.
