How about getting a knock sensor too.
I'm a little confused about the question. The tps are the same in a turbo or n/t of the same year/series. Same with the water thermo. The afm are a bit different, but not that different.

well im doing a experiment putting a turbo II parts in my gslse block and im doing a ecu swap because i ont hav enough money to buy a haltech now, ok i need the AFM, water sensor, air tem sensor, boost sensor, knock sensor, TPS, CAS with coils wiring harness and ecu, what else to at lease run my car with a turbo II ecu? thanks

eddierotary,
This is what I'm doing. Take the FC wiring diagram and trace out all the wires coming from the ECU. There are three plugs. The wires, as you could imagine go to alot of sensors, switches, and other things. I'm moving over everything from the FC to the FB. Some switches don't have to move (neutral, water temp, heat hazard) and I imagine some of the temp sensors may be ok but I haven't checked their ratings yet.
If you have wires from the FB harness that can be used in the FC ECU (like the a/c relay), I think you can push the pins out of the FB connector and insert them in the FC connector. Also, the 20,000 mi sensor switch I'll just leave open or jumper, depending on how it works, the FB doesn't have one.
This is a brute force method, bringing everything over. I don't know specifically what could be omitted and what function that would have in the ECU in regards to ignition and fuel delivery. And yes I'd mover over the knock control unit also.
One nifty thing, wire the ECU shift light to our "overdrive" light. Unless you have automatic, this light is not being used. The shift light tells when the optimum MPG shift speed occurs--yea I know big deal.
I'll try to get more of this on paper and post it on my web site.
Good Luck,
Scott
