First off...1996 Firebird 3.8 v6

I've got an oil leak that's coming from just above my oil filter. The leak is actually coming from a connector or sensor. Basically, it's some sort of electrical connector. Apparently the seal has gone bad on it and needs replacing. Can anyone tell me what this plug is so I know what to go get? OR, does this mean that something behind it has gone bad and the problem requires more than just replacing a plug? I took a pic with my phone. If needed, I can email it to show what I am talking about. Oh yeah, and it only leaks when the car is running.

Here's a pic where the leak is coming from:

That's your oil pressure sensor.
