Okay I like the Throttle body. But I do have a question if I have a ford harness. What do I need to do to make it work with the supplied GM TPS and IAC? or will a ford one fit on these?

[Matt Cramer]

It depends on whether you're using stock Ford engine management or a standalone that supports GM hardware. If you want to use a Ford IAC valve, your best bet would probably be to tap the holes on the IAC valve body for hose barbs and remote mount the IAC, with the inlet plumbed upstream of the throttle body and the outlet plumbed to the plenum.

Well I was planning on using your Megasquirt PNP system for the fox body but I wanted to eventually use the throttle body on a custom injection. Can I rewire the stock harness to work with this or would I need to do all that to the iac??

[Matt Cramer]

That's doable; you need to add 4 wires to the adapter harness (pins 25, 27, 29, and 31) to wire up the IAC.
