The sensor is on the bottom of the plenum, mounted vertically near the rear. If you didn't plug it in when the plenum was off it's a PIA. I made that mistake once and was able to connect it with a long screwdriver and a pair of long handled needle nose pliers. But it wasn't easy.

Good luck,

Matthew

It connects by the firewall in the rear area behind the distributor.

The connector is behind the head on the driver's side. It's part of the very large engine control harness that goes to the ECM.
