i have a 90 civic si with an obd0 to obd 2 coversion harness running an obd2 computer and i am trying to wire in my air fuel ratio sensor into my computer so it can read it. ive looked around and it seems like they have 29 different answers on which wire is the sensor signal input to the computer. does anyone have a pinout of the obd2 computer from a reliable source or know which wire is the signal wire?
