Prelube engine question

I have the sensor (low oil?) out of the side of the oil pan since the engine is out of the car.

I want to pre-lube the engine, but there is a hole in the pan... Am I missing something? Any trick to plugging this?

Ha, yeah I figured that would raise a few eyebrows.

Yeah I've basically been following the steps on the Boxwrench engine reubild dvd. It's been great for a first timer like me so far. Not to mention this forum and you guys have been super helpful.

Anyways, I'll get that plug and prime the engine tomorrow. The only thing left after that would be distributor, plug wires, etc. Then it'll be ready to drop in. I'm pretty stoked!
