Omar,
I went out and bought a haltech branded IAC and IAC housing. I believe the IAC is actually a 4 wires not sure if it's a bypolar or unipolar IAC. I believe it's a GM/DElco style IAC.
Will be installing the M400 on a 3SGTE MR2 with custom instake manifold.

If it is a 4 wire valve it sounds like it is a stepper motor, this is not the best thing to use, I would use a PWM controlled valve. A 2 wire one from a Ford would work ok, much better than stepper motor idle control.

Thanks for the reply Ross.. Can you elaborate a little more on this?
I haven't drop in the idle air control motor cause I'm thinking maybe I can get by without using one.
Can you tell me more about the 2 wire PMW IAC please?
Cheers
