Hey guys -

I'm installing an Air/Fuel gauge in my Civic, which is a pretty typical install for most on here, but I need to know which wire to tap into at the ECU. There are TONS of wires coming out of that. Looks like 4 wire harnesess with 12+ wires each. Does anyone know or have a diagram so I don't splice the wrong wire. Or else is it easier to tap in somewhere else? Thanks!

 

Bump.

 

What - Nobody has ever installed an Air/Fuel Gauge B4??

 

ummm ****, hold on let me think. I believe that youll have a red black white and green i think> Red is power black is ground white is the led and green goes to the O2 sensor.

 

Thanks for the info - However I'm looking more specifically which wire on the ECU connects to the O2 wire coming from the gauge. Thanks!

 

u shouldnt be running one to the ecu
