blue, brown & yellow/green vs black, white and green

I am wiring in a pump for a pond. The wiring for the old pump has a blue wire, a brown wire and a green/yellow wire.
1- Which one is the hot one that I wire to the black?
2- Which one do I attach to the white?
3- Which one do I attach to the green?
4- Which one is the ground?

you need to look at the wire diagram and find where it says L and N. It will tell you what wire is the Line(hot) and what wire is the Nuetral (N) I am guessing that the green/yellow stripe is the ground. Also, check the voltage. Make sure it says 110v. It could be 220v If this is the case the wire diagram will have 2 L's on it.
Let us know

Thanks for the prompt reply, however I'm still in the dark (literally ....the sun has gone down). Hopefully someone can get me a reply by morning when I can get started again.

Problem is, there is no "book". It is an old submersible pump and I am rebuilding and refilling it. It works, but when I took everything apart, (the wiring was hard-wired in a box that I can nolonger use), I lost the connections. I am putting in new wire. If the green/yellow is the ground for the pump, then I would wire it to the green wire of my new wire. I know Black is the "Hot" wire and White is the "neutral" for my new wire, but is the Blue or the Brown the "Hot" wire for the pump?

It is a 110 not a 220. I don't have a flashlight and cant read what is on the pump. It apparently used to be a plug-in which had the plug cut off when hard-wired. My guess is that it is from Europe or Japan and they have different colors for their wires.

There is not any wire diagrams on the side of the pump anywhere? There should at least be a nameplate on the motor part of the pump. If not, I would put the black to the blue and the white to the brown and see if it runs. If it is backwords, it will trip the breaker.

Hip, Hip for Michigan!!! I wired the black to Brown, green to green/yellow, and white to blue and water started pumping!!!!

Hopefully, it will be clean enough tomorrow morning and I'll go get some goldfish to get it started.... First one in will be named Michigan. Thanks for your help.
