TPS Linkage?

Hello again, I recently joined this forum, and love it. Lets see if You can help me again!!

I (think) I figured out what my 4000 rpm / wall / cutoff thing was, since it happened at seemingly random intervals.

Right where the tps is located, I am missing the linkage that would actually move my throttle to press-depress the TPS to actually change voltage. It has been stuck wide open since I have got the car. Idle change is crazy, goes anywhere from 750-2000 rpm's on a whim.

heres my question, can anyone post up a picture of what this set up is supposed to look like? My first RX-7 was a N/a. can I take my S4 non turbo linkage, and put it on a s4 Turbo TPS???
Please advise.
Thanks!!!

no linkage per say on that side except for where the OMP rod connects to the Throttle body.
The TPS is connected by 2 10mm headed little bolts to the Throttle body and the plunger sits up against a Piece that is on the TB shaft.When the shaft turns OPEN then the TPS plunger is allowed to open all the way.
That part can be taken off a NA TB.
Sorry no pics..I may have some old S4 TII gutted TB though.

Im looking for the shaft then I guess??? or whatever presses us against the TPS itself. I have the 2 pulleys opposite from the throttle pulley, on the rear of the TB (from the front of the car,) I am missing a piece on the front, that goes from the second pulley to TPS. The 2 pulleys on the front of the TB are there, there is nothing connecting them, causing a reaction to open/close the TPS.

I have a TON of s4 N/A motors at my house, is it possible to take the parts I need off of an S4 n/a TB?? Or am I going to specifically need a S4 TII?
