Wireing up my air/fuel gauge to ecu?

Does anyone know witch pin (wire) to run the air/fuel gauge to the ecu? (OBD2)

you have a 98 integra which means OBD II look it up in ur haynes service manual and it will tell you there's 4 wires from the O2 sensor to the ECU 1 of them is the signal wire i dont know what the OBD II color is yours but for mine which is OBD I was the white wire with the red on it but the Haynes service book is the best bet to look

cool that is what color the wire is on the o2 so maybe it will be the same.

im assuming you have a b18b. send the wire to the white wire on the o2 sensor harness.

PS: on the harness ecu side, the color is white/red. i believe that is d14. check yourself to confirm.

Thanks
