ZXT_bean Posted April 20, 2009 Share Posted April 20, 2009 well I finally got it running yesterday. But im not getting any O2 sensor voltage. I have 3 different ford 4 wire o2 sensors. bosch 88926A0 (from 99 mustang gt) denso 25930 (from 99 mustang gt) ford f5mf-9f472-b2b (from late 90's taurus) Ive looked though the mega manual and ive found other part numbers, but I was courious if anyone had used a 4wire ford sensor. the wiring ive found was the 2 white wires are for the heater circuits. both go to 12v+ the grey wire is the sensor ground and the black wire is the signal wire to the MSII. I can find all the info in the world about a wideband setup, but very little on narrow band o2's. any help would be greatly appreciated.

Guest Rolling Parts Posted April 21, 2009 Share Posted April 21, 2009 "the wiring ive found was the 2 white wires are for the heater circuits. both go to 12v+" Actually, one has to go to +12 and one has to go to Chassis Ground. It dies not matter which since it's a simple resistor circuit. Quote Link to comment Share on other sites More sharing options...
ZXT_bean Posted April 21, 2009 Author Share Posted April 21, 2009 so the grey wire and one of the 2 white wires have to go to ground. ok im going to go try that right now. thanks Quote Link to comment Share on other sites More sharing options...
