Thread: Holley Sniper 92mm with OEM IAC?

    With the key in the on position, you can change the IAC Park Position from zero to 100% & back to make sure the IAC cycles through its range. You can do this before installing the IAC into the throttle body. Andrew

    I'll do this to verify. Thanks.

    Read section 16: http://forums.holley.com/showthread....neral-IAC-Info (General IAC Information - Read "IAC NOTES")
    So if I repin according to the GM diagram of section 17 in the post you linked above, would that be the correct way to use a GM LSx IAC with the Sniper 92mm TB? I prefer to stay OEM sensors as much as possible. I’m running Terminator X. Thanks for sharing your knowledge!

    Sorry to bump an old thread, but it would help if Holley would update their information.
    Has anyone verified that what Danny suspects is correct?
    My use case: Sniper 92mm TB, I need an IAC solenoid. I don't mind swapping wires around if need be.
    Fantastic forum you guys have here. Thanks for the information.

    The Holley 543-34 LSx IAC motor is the only GM LSx IAC motor Holley sells. So it must be correct for a Holley EFI LSx main harness and GM LSx type throttle body. (It'd be nice if Srkelvin updated this thread.)

    Thank you, kind sir. I don't intend to be a nuisance, but when we say "a Holley EFI main harness", it includes the Terminator X Max (and any current Holley EFI) harnesses? Thank you for your time.

    Any Holley EFI LSx main harness. The non-LSx Holley main harnesses use a different IAC motor.

    Has there been any confirmation that the 543-34 is the correct IAC for the 92mm Sniper TB? Did the IAC PARKED test with the 543-105 and an HP and it does extend nor retract. Tested it again with a Terminator X and it did not work. Took the generic IAC that was being used with the Terminator X and tested it on the HP and it tested fine. So it would seem the 543-105 is either defective or needs pins swapped as previously mentioned. I would prefer to used the correct IAC, untouched. Thanks.
