The oxygen sensor plug came off it's wire on my EA82T. The only loose wire I can see off the harness is a white wire with gray jacket, does this sound like the right one? I'd like to get the closed loop portion of the EFI working right.

On my spfi swap the single white wire w/grey jacket was the o2 wire.

Ok, that's probably it then. I'll have to do that tomorrow, need to do a few other things in that area anyways.
