I hooked up my A/F and tranny temp tonight, but neither of them work. What wire do I splice into on the PCM for the A/F guage?

 

You need the purple or purple/white signal wire from the O2 sensors (one is left side, other is right), and they are connected to pins C8 and C20.

 

Would this wire be located in the wires going to the pcm? I see 2 purple wires (thicker one is the starter I believe) and the other one is what I have it tapped into....

 

The purple harness wire from the passenger side O2 sensor is connected to pin #C8 (grey connector) on the PCM. Look at Shoebox's pinout diagram to make sure you have the correct wire.

I don't see any other purple wire in the "C" connector. The purple/white stripe wire is on pin #C20.
