Need help installing Air/Fuel ratio gauge
Hi all, I am a newbie here and I am exciting to see so many Celica lovers here as well.
I purchased a Autometer air/fuel ratio gauge recently. Try to install it myself but couldn't figure out which wire should tap into in ECU. Even after check out the pinout diagram this site provided, still can't figure out.
So if anyone out there did this mod, please give me some tips...any hint helps...
