Install of new bilge pump

i'd like to install a second bilge pump. I haven't converted to negative ground (and don't plan to, if I can help it), so i'm wondering if I can purchase a negative ground pump and rewire it so it will run on positive ground--kinda like rewiring the the fuel gauge. since fall is approaching I figure I can find a decent pump on sale. Anyone ever do this or have any thoughts?

Unless I'm missing something, the pump will work for you right out of the box as long as it's wired correctly i.e. put the red wire of the pump to ground.

That is correct.. But a lot of times power is Brown Ground is Black so black to switch power to frame of car, Now if you put a auto float in it gets real fun!

And a good place for on off switch is on side beside seat bottom.

huh, i guess i figured if i wired it positive lead to ground that the pump would run opposite what it should.
