Just got an autometer a/f gauge. Anyone know which wire to tap off of the o2 sensor to get the correct reading? My options are Tan/ Black with Pink strip / ro Pink with Green strip. Thanks for help.
tap into the ECU
Go to the Apexi site and look for the diagram under the Wiring instructions for the auto timer. it will show you where the pin out for the 02 sensor is. then just take the purple wire from your gauge and tap it into that wire. You will also want to use the ECU's power and Ground. You get better results that way.
Good luck,
In your little diagnostic connector by the battery, there is an "O2" terminal. It directly connects to the O2 sensor. You can splice it in there, quite easily without butchering any wires.
Or do it really right, and just get a wideband. I had a narrow band autometer, junked it after a week really is just a useless light show, and went with AEM wideband. Check out www.plxdevices.com for a cheaper one, or horsepowerfreaks.com for a decent price on AEM.
Hmm, is it possible to just buy a wideband o2 sensor and then plug it in to the stock ECU or do you have to go with one of the kits that include their own displays'.
