Okay guys, I found this while doing a search on Yahoo!:

So now I'm almost convinced that those two lines that I saw dangling are for the oil pressure sensors. I'm thinking the black one is for the actual sensor as shown in the link above and the green ended one is for this black thing with the bronze tip sticking up next to the sensor:

The only thing is that the lines are too short to go all the way down. Anyone have any ideas???
