Hey

Is there a chart out there SHOWING what wires are WHAT in the PCM?

I need to find an O2 sensor wire in my PCM in my 2002 Jeep Liberty LTD. so I can connect an Air/Fuel Gauge.

please help it's driving me NUTS.
Autometer said it was Pin 24 a Black wire with green stripe, but that wire doesn't do anything on my Gauge, even when giving it gas.

thanks!
Anthony
