I have a 1992 Pontiac grand prix. the o2 sensor is not hooked up. I put a new one in but the connection to the pcm is no where to be found. I need it to be connected to pass emitions. where do I go to find the connection at?

figuring it out

You mean that there is no single wire connection off then standard harness?
Not that I'm Pontiac familiar, but from what I've seen there are various versions - all EFI but some with two sensors - and all (from memory) single wire. If it's the st'd loom, there should be a termination for the O2 sensor.
Is the loom st'd or has it been butchered?
