you need to use the one that your ecu is for. if you upgraded to a y8 ecu or chipped p28 and will tune it, then you'll need to do the 2 wire conversion and wire to the iacv on the back of the manifold. if i remember correctly you'll need to also use the y8 tb (or one that doesn't have the iacv on it) b/c it'll cause an idle issue b/c the iacv on the tb will no longer be active (can't remember exactly, but i no longer use my y7 tb and i wouldn't have removed it if there wasn't a reason to).
