I just went and rechecked and it is the blue wire and tan wire in the TPS that are used for the voltage reading. Disconnect the port head sensor(the one with 2 wires), backprobe the blue and tan wires with a good voltmeter set down to read less than a volt accurately, turn the key on but don't start it, adjust the sensor to .25 volts optimum(.2-.3 is acceptable range, but .24-.26 is best for a baseline), tighten it down and re-check then button it back up and run it. You may need to make some small adjustements to it to fine tune the idle mixture, but ALWAYS do it with a meter hooked up as you will see how touchy the adjustment is.
