I'm pretty sure the ECU needs that wire more than your A/F meter.There is only one wire on a 92 teg's oxygen sensor. And that is the one you are after. Unless you've converted it to a wide band..
92+ is obd-1 and uses a 4 wire...There is only one wire on a 92 teg's oxygen sensor. And that is the one you are after. Unless you've converted it to a wide band..
If it's a narrowband gauge it MUST be used with a narrowband o2 sensor (i.e. tie it into your factory o2 sensor)
If it's a wideband gauge it must be used with a wideband o2 sensor (typically aftermarket)
its an red, purple and black coming off the guage. auto meter pro comp ultra light guage.
Don't confuse that red for 'power'... The gauge will work and the rich/lean indicator will light up with the signal of the o2 sensor. That red wire is for the backlight so it lights up when you turn on your parking/headlights.red would be power for the gauge to come on, black wouls be ground. the purple wire would be a signal wire that would get tapped to your signal wire on your stock o2 sensor. if it was a wideband gauge, it would have a wideband o2 sensor with it, and a harness and other stuff. i think the signal wire for a 4wire o2 sensor is green, i think.
