Pinout help needed.

[RICHIE HIGH PSI]

I need to know where all 4 IAC wires are located @ the ECU.
Thanks

IAC B LOW C3 grn/blk

IAC B HIGH C4 grn/wht

IAC A HIGH C5 blu/wht

IAC A LOW C6 blu/blk

HTH!

IAC B LOW C3 grn/blk

IAC B HIGH C4 grn/wht

IAC A HIGH C5 blu/wht

IAC A LOW C6 blu/blk

HTH!

anybody know what each wire represents?
want to make a plug to test these outside of the housing.

A and B are the two coils of a stepper motor

A and B are the two coils of a stepper motor

OK
so there are two sets, and powering one set, drives in and powering the opposite set will drive out?
thank you.

No, not so simple at all. Applying constant power and polarity to the coils will just cause them to jerk into one "step" position, some fraction of a rotation inside which likely moves the needle some tiny fraction and locks there.
(not had one apart to see what it does mechanically)
UNIPOLAR STEPPER MOTOR would be the keywords

IN your starter or drill the commutation is done inside the motor to apply power to the next set off coils to keep things going. Steppers are externally commutated brushless motors, the ECM does the switching of polarities and coils to create rotation here.
