Perfect. I love this. I think this is exactly what I need. Two questions: I plan to have the Humminbird AND the Garmin Navi on the same switch. Surely these two don't draw too much power??? Second, "any of the 12v- spades" means exactly what? I'm guessing there are some back there with a minus (-) next to them. I'll look for that.

Thanks again!
