mpfi injector harness

k i am bout to convert my cfi falcon to mpfi,i got 2 types of harnesses.
both are bout the same except for a plug on the throttle body.
one has the right 3pin oval plug the other has 2 3pin circle plugs.
the one with the bigger 3pin oval plug is brocken.
Why would there be 2 types of mpfi harnesses?
Can i still use the 2pin circle type with a bit of modding or do i need one like the brocken one?

Re: mpfi injector harness

What EFI are you using?
EF/EL, you'll want the single oval plug.
EA-ED, hunt around for an early EA manifold. You'll find it has two TPS on it which will plug into your two-plug setup. It was an early thing for 4speed autos, they quickly went to just taking the feed off a single TPS. Perhaps there were some double units left over from the CFI to be used
