Default Simple IAC Valve Question

Doing a TB bypass and cleaning. So far so good. Removed IAC and cleaned.
Now getting ready to set the minimum Idle speed. According to the book
"disconnect the distributor set-timing connector" Is that the same wire you disconnect when you time the car? The book calls that the "Electronic Spark timing(EST) connector. If its not the same connection whats the correct connection and where is it?

Thanks Guys

C'mon guys, this should be a no-brainer for you. I gotta get this car back together today. Tomorrow I'm taking out the new 'flavor-of-the-week' ,she's not going to be impressed If I pick her up in the minivan (hehe).

Yes, it's the same connector that you disconnect to set the base timing.

Thanks Mike. I always second-guess myself when it comes to the vette.
