I need an ecu pinout for a 1999 civic si so i can wire up my a/f gauge also if anyone knows what wire on the 02 sensor i should hook into that would help. Or can i just run it off the ecu..because everyone is telling me that i can do that just so find a pinout...any help would be greatly appreciated...thank you
