My intention was to use the Suzuki throttle position sensor to sense the main throttle blade position. This will require some experiments of which I completed the first. According to my tech the ford sensors normally work on 5 volts. Full throttle will detect as somewhat less than 5 volts. Closed throttle above zero a small amount.

I have a variable power supply that I can supply 5 volts. I connected plus and minus to the Suzuki yellow and blue lead which are low in the pictured plug. I sensed the voltage at the black wire which is high in the plug. Firstly hooking up the power supply drew less than .01 amps. This is good as things are not overheating. Throttle closed was about .010 V. Throttle opening saw a nice smooth increase in voltage to about 4.9 or so fully open. I think the ford computer will readjust to small differences in wide open and full closed as there is bound to be a 5% or so variability in one part to the next. Anyway another short test of the car will see if I am matching closely enough. Use of this TPS will make the assembly neater by requiring less fabrication.
The TPS slides down a flat blade that becomes the throttle shaft. You can see the secondary throttle plate blade which is similar. You also get a spare TPS with this throttle body as the Secondaries have an identical position sensor that will not be used.
