Need Help Now! A/f Gauge Install!

[97 MGT]

My buddy and I are working on my air fuel gage now in my 97 gt mustang.
We dont know what the sender wire on the 02 sensor is. Is there a way to hook it up to the ECu somewhere or to the wireing harness?
Please help ASAP!

It's the black wire. Connect the purple wire from the gauge to the black wire on the 02 sensor. Or you can find the spot on the PCM. Good luck, it's not hard.

I was told the Fuel/Air ratio gauges are useless because they are not very accurate. We can only connect the gauge to one of the two o2 sensors in the h-pipe.

How accurate is this information?

They shouldn't be used for anything but a lightshow... but it's a cool lightshow never the less.

The A/F gauge isn't one I went with, but I don't know if I'd call it useless. I suppose if you have everything else it's always nice to have a light show

No your wrong, there not accurate if you have a bad sensor, yes you can connect it to both sensors you just need to put in a switch, so you can switch from one to the other
