difference between an fc and fd tps on a microtech

Just wondering if I where to get one of these CNC 80mm throttle bodies that mate to the stock intake manifold but use a tps from an fd would it still work with my microtech? I guess this is really just a general lack of knowledge on my part with anything fd related but I don't want to get this throttle body and then find out that the microtech wouldn't work with it. Does the fd tps have more than 3 wires or would it still use the same 3 wires that the microtech uses? Thanks anyone that can help....

you leave off the fourth wire disconnected

if your looking at the TPS plug,, with its twin locating notches upwards
then position 1 is the brown ( ground )
position 2 is unused
position 3 is the blue 5V
and position 4 is the grey signal

You can use any TPS you want.

However, those CNC throttle bodies eliminate the progressive throttle on the stock throttle body, so you will have all 4 intake ports open at once. Port velocity will go in the crapper and you'll need twice the primary injector PW at low loads then you did before as much of that fuel is now sticking to the wall.
