Can anyone tell me how to wire in a 5 wire bosch 4.2 o2 sensor or even just tell me what the 5 wires are?? witch ones ground, positive ect.... for all 5 wires?? thank you jarven93 will be installed on 93 civic ex d16z6 p28 ecu vtech. wire colors are...RED, Black, yellow, grey , white.

 

Do you have a wideband controller or an aftermarket ECU that can read the wideband signal? I'm pretty sure it won't work if you wire it directly to a narrow band Honda ECU.

 

i just want to wire it to a air fuel gauge. can that be done?

 

You need a controller in order for the gauge to read the signal from that particular WB O2.

What AFR guage do you have? Is it a wideband gauge or an autometer air fule ratio gauge (narrow band)?
