This diagram shows it on the front of the engine under the intake manifold, roughly. It seemed to have moved a bit right in later models.

I think it was packaged with an shiny "aluminum foil" heat reflector. Replacement reflector is $5.

The connector is delicate after all the heat and oil exposure so be really gentle with that. Replacement is expensive.
