O2 sensors

[Steves LX]

I picked up a Air to Fuel Ratio guage today. The one wire on the guage needs to hook to the O2 sensor signal wire coming off the computer. Does anyone know what color wire from the computer I am looking for here or what pin #?

I had one like that many years ago. It wasnt worth a crap for tuning but it was fun to watch it bounce from lean to rich as I drove. There was an issue about the voltage coming from the signal wire that didnt match up the the signal voltage that the gauge needed to see. I dont remember what wire it was offhand, but if you dig into a Haynes manual the wiring section should have it listed on the schematic.
Good luck with it!

I can't remember which one but you can probe them with a volt meter until you find the one that registers volts.

You have to be at WOT for it to stabilize and who can look at that gauge under WOT if there car has any balz.
