Can I use an S4 TPS on my S5?
I plan to replace the full-range tps using an s4 type due to hesitation above 6000rpm and unfortunately wreck yards around here only has pre-89 rx7s.

Short answer: No. Long answer: Well, kinda.
The actual sliding potentiometer that is the TPS is the same for all 2nd gens. The TPS assembly for the '86-88 cars is the same, but there are different TPS's for the '89-91 NA's and Turbo's.
There are 3 wires going to the sliding potentiometer - power, ground, and signal output.
The pot is held on to the bracket by 4 little metal tangs that are bent to hold it on the bracket.
So, with that in mind, here are the possiblities -
- If you have an '89-91 NA and want to use an '89-91 Turbo TPS, you can bend and remove the TPS's and swap the brackets out. No wiring or anything needed - plug it in and go. The plug is a different color, though, but that's just to make it easy for Mazda to tell which TPS is which.
- If you have an '89-91 car and wish to replace one or both of the TPS's with an '86-88 TPS, bend the tabs and remove the TPS's from the brackets. Install the new TPS onto the '89-91 bracket, and splice the wires into the '89-91 plug.
The only trick here are those metal tabs - they probably aren't rated for multiple removals and re-installations. It's not hard to do, but you want to do it right the first time.
