i am brand new to this site,.. i was directed here from a friend on Ok-Speed.com.aight,... if anyone has any knowledge on hooking up a A/F gauge on a 92 Prelude please drop some of that knowledge on me. I just hooked mine up, right now the gauge is pegged at rich (only one block lit up. the power and ground are easy, the part i need help with is which wire on the O2 sensor do I tap into. Right now its tapped into the white wire after the connector from the O2 sensor. I have 4 wires coming off of that connector white, orange, black and green. i feel kinda stupid asking this, i mean the damn gauge only has 3 friggin wires coming off of it. anyway, can anyone help a bruva out??
