Can I adjust my TPS on my S5 using test lamps?
 

Hi, on this page http://home.rmci.net/panther/tps.htm it says that it's also for 89-91 RX-7.
I built the test lamps but I can't seem to find the little green connector where you plug the lights in.
I found a white one, but it only has 2 holes.

did you look around the oil filler neck just behind the solenoid valves?? you should see it hanging down there.

I can't tell what kind of car you have by your profile. NA or Turbo. If Turbo the above post makes sense. If its a NA, then the green connector is in front of the right front strut tower. Might be hidden just a bit under the air filter. Aft end of the air filter housing.
