Celica Forums General Discussion Exterior autometer fuel/ratio gauge

If anyone has put this on their car, what's the oxygen sensor signal wire? Which color is it?

c'mon ppl-need some help here!!

i'm lost

blue

I don't have a pic, BUT if you lift up the carpet on the passenger side, by the console, where it starts to go up towards the dash, you will find a blue wire with a small plug. That is the o2 wire you are looking for, There is also another o2 wire but it is the one from AFTER the CAT and you don't want that one. Hope this helps ya.

thanks for that info! i plan on installing one very soon
