IAC not responding while on engine dyno, any ideas? The C100, C101, C105 connectors on the shock tower, I fed + volts to get it to turn over fire up and feed the maf. There are two pins labled IAC items on the C101 connector that were open, and IAC were constantly reading 0 at idle cruise wot etc. Do these need 12 volts, or do they switch polarity, or alternate voltage to retract/extend the IAC pintle? Everything else we got working on the dyno with a minimum of wires added to the engine harness
