Default .Want to wire FD TPS onto the FC wiring.(how?).

I am "attempting" to put an FD upper on my FC TII and I need to know How to Wire the FD TPS onto the Harness.I have the TPS Connector.
another quick Question: I am running RTEK 2.1. Can I run the FD TPS with an RTEK?.or should I just Say Frigg It,and Put on the TII upper and wait until I get a Haltech?Thanks Gents.STYX.

FC ecu does not use a full range tps for anything other than MOP operation on the S5, and the TPS on the fd is full range. I'd guess you're not going to have alot of luck with it though it MIGHT work if the ohm range is the same between the two which you could test for with a DMM or check in the FSM.

As for wiring, you'll need to look that up in the fsm as well. Just match up the wires, one is +5v, one is ground, one is for the sensor output.

I thought the fd tps had both a full range and narrow range, so it could be wired on both the s4 and s5. I think this is way to wire it on an s4

FD tps S4 harness
ground - black/brown ---- brown/black
narrow tps- green/red ------ green/red
5 volt ref. - brown/white ---- brown/white
tps - black/green ----- not used
