yes the green and black wires.
All you need is a multi meter flat head screw driver and 30mins.

If you need 4 turns of the TPS screw to adjust things "properly", then there's something else seriously wrong. The proper procedure is below:
Adjusting the TPS is a simple maintenance item that should be preformed at any oil change. The benefits include better gas mileage, better performance and a smoother idle. Adjustment only takes a few minutes if you follow the directions below.
What You Need
· Ohmmeter
· Flathead Screwdriver
· Half an hour
How To Adjust
· Warm the car completely by driving for 20 minutes
· If your car is a turbo, remove the intercooler. Loosen the hose clamps on the inlet and outlet, remove the vacuum line, and then remove the four bolts (I believe 11 or 12MM). Lift off the cooler. Do this quickly so the car does not cool.
· Unplug the TPS. On 89+ cars, you want to unplug the connector leading from the lower TPS.
· Hold the TPS connector so the hump points up. Connect your meter between top connection and rightmost connection.
· Adjust the stop screw until the meter reads 1K (1000 Ohms)
· Plug the TPS back in
· If necessary, reinstall the intercooler. Don’t overtighten the hose clamps
· Drive the car for a few minutes, then repeat the procedure
