Need help with PSU for MVS-4-25

I was able to pick up an MVS-4-25 in great shape.
It needs a new PSU, and I have one, but there are wires all up in this guy.

Any docs or guides to getting this guy powered up?
The spec sheet is pretty vague, and in engineering speak.

Did you buy the original type power supply?


Can you take pics of what wires are where
