well u notice for the one it says A/T only. its for auto tranny, park switch, reverse switch whatever the auto trans uses for plugs and sensors.

the one with the 3 prongs i think has the starter signal in it (if its a black with red stripe wire).

S14 Tranny Swap - Electrical Connections find the 5 speed conversion - it tells you how to eliminate and/or change those plugs to work.
