I'm buying an Autometer Air/Fuel ratio gauge and am wondering which wire on the PCM I need to splice into.

Thanks guys!

 

Just to elaborate more, I think the PCM has a wire that transfers information on the O2 sensors. Could anyone tell me which wire this is? I need to tap into it for my gauge. The color or any other info would be great. Thank you guys

 

You will have to buy a WideBand O2 sensor and gage. If what you purchased has the O2 sensor with it, the wire will come from the O2 sensor.

 

If its a narrowband you can just buy a pigtail and just plug it in to the o2 sensor. So no cutting or splicing wires.

 

Thanks guys. Yes it is a narrowband AutoMeter gauge. Bluebird, could you explain a little more? I've never touched the subject of O2 sensors, I don't even know where they are in these cars.

Thanks for any help, I appreciate it.

 

Go here and scroll down to A/F gauge pigtail. It makes it a lot easier with no splicing into the harness or anything. The o2 sensors are in the y pipe, you cant miss them, they thread into the side.

Go here and then click on your specific year to see the pinout and wire color for your car. Remember you want the "low signal" for the one returning from the o2 sensor. I suggest the pigtail route myself. But, here is the info if you want it.

I just wish this info was a sticky in this forum also....seeing how wiring info is asked all the time here.....mods?.....admins?
