Mystery Plug
Does anyone have any idea what this plug is for. I was replacing the oil pressure sending unit and saw this random plug that was not connected to anything right behind the driver side valve cover. The wire is short and I don't see anything near by that it would have plugged into. Everything on the car is working and no check engine light.

Re: Mystery Plug
Same as everybody else that asks about it.
It's the "mystery plug". Well and widely known to just ... be there. Doesn't plug into anything in a fully assembled car. Best guess is, since it's ign & ground, that it was used by the factory (ies) for testing the wiring, ECM, sensors, injectors, etc. etc. etc. at the plant where they build the harness, and then similarly later on at the engine plant, to hook up power to it and exercise everything before it went to a vehicle assembly plant and got put into a car and FAILED, after which it becomes EXPONENTIALLY harder to take back apart and fix it if it's focacta.
Just common-sense ordinary industrial common sense to anyone that's ever worked in an industrial environment and had to, in spite of "chain of command", establish common sense over their overeducated under-mentally-endowed moronic moron of a moron "boss" who was utterly totally and completely lacking "common sense". Butt of course that's NEVER happened to ANYBODY, eh??

Re: Mystery Plug
Ok ok. Thanks for the help. I've just never noticed it before until now and was afraid that something became unplugged.

I think there must be a great deal in common between our career trajectories.
