Looking under there today and noticed alot of fluid seems to be lurking around the pan area. This plug I took a picture of seems to have alot of gunk around it along with some fluid. Is that the speedo cable? The speedo hasn't worked since I've gotten this truck, I'm thinking this could be why. Would like to figure out why it was leaking as well. Took some pictures of the seal around the oil pan. Can't really tell if it's leaking from the seal, but looks rough.

That's your speedo cable and vacuum modulator. I'd clean all the oil off it and drive it a bit then you could get a better idea of what is leaking.

Common cable connector leak.But I'd take that advice and spray it all off good.
