In my first reply I said to hook up the 3 prong variable pot to ground on one side, but that was wrong. The 3 prongs should be hooked up so that the output signal from the MAF sensor goes to one end of the pot and the 5 volt reference wire to the other side of the pot. The middle wire then coming out of the pot will be the new singal to the ECU. By turning the variable resistor or pot one way or the other you can bring your MAF sensor output into the correct range.

Again the pot does not get hooked up to ground.
