Accufab 4150 TB IAC wiring

Ok so I'm buying a 4150 throttle body from accufab and it comes with the GM IAC and TPS. I figured out how to wire in the TPS to the ford harness but I haven't found any solid info on how to wire the 4 wire GM IAC into the ford IAC harness, if it can be done at all. I realize they are two different types of IAC sensors as well. Does anyone have any information on this? I'll be using a megasquirt pnp system. Thanks

Is that the MSPNP, a DIYPNP, or a regular MegaSquirt with some sort of adapter harness?

Some of these cannot be set up to control the IAC valve; others can, but you'll need to run new wires for it.

It will be the MSPNP system. So i'll just ditch the IAC, no biggie. I've heard of people tuning around it before. Thanks!

I'm afraid the MSPNP has no stepper IAC output, as it was designed to work with the stock Ford IAC.
