On the newer FAST manifold they have re-located theMAP sensor from the back of the manifold to the front---reason is that their is very little clearance next to the cowl and it wouldn't fit or it would break off---I've seen MAP relocation kits on the internet for this same situation--I belive the kit somes wih a pigtail extension---I would also think you would have no reason to rewire the MAP to the ECM--just use the existing pigtail--Is there another reason why you think you would need to re-pin the ECM ???

I would recommend that you remove the MAP sensor from the Alky kit and wire it into the factory wiring and then tap off the reference wire (should be green) to trigger your Alky system.
