i was just wondering if anyone knew which of the four wires on the o2 sensor is the sensor wire to the ECU on a JDM B18c, or atleast the USDM B18C1. I need to hook up my Greddy air fuel gauge and i need to know whuch wire i need to hook it up to. thanks for anyhelp.

 

does anyone know the 02 sensor wiring for a 95 civic dx?

 

its the white wire.

 

Wht/red

 

just tap into the wire white off the o2 sensor instead of the ecu. much easier.
