Wire up the TPS the same as the new digital units as shown here;
http://www.pdfdownload.org/pdf2html/vie ... ctions.pdfFor setting up purposes leave the pink wire disconnected and then turn the ignition switch on (without starting the car) and arm the nitrous system.
Plant your foot to the floor and then adjust the potentiometer until the LED either lights up or just goes out - depending on how the adjuster is originally positioned.
Once you have the adjustment in the right ball park, adjust the setting so the LED comes on when the throttle is operated to say approx. 90% of full travel.
Connect the pink wire and test that operating full throttle activates the system.
