When I wired my pumps in I used the switch to power solonoids that in turn swithced the pump on. The reason for this is so I didn't have to run heavy wire from the switch to the pump. Light wire from switch to solonoid, heavy wire from solonoid to pump. Of course, the solonoid has to reverse the polarity going to the pump to allow it to run in reverse. I don't remember how I did this, but if you don't get a response from someone who knows, I will look at my boat this weekend and send you a diagram.
