Not a dumb question at all BIG BRANDO! I had to look up that information myself.

The brown and blue are European standards. Brown is hot (i.e. red), blue is neutral. Leave the black wires connected to the capacitor as they are. Please post back here with the results of your pump.

I emailed the ebay dude and he told me to ship it back for a return (good news). I emailed him back with some questions first, as shipping is $20. Grrr.
