So I'm trying to figure out the wiring for the bilge pumps and the Mayfair float switch on my boat. I found 2 good wiring diagrams on here so once I figure out which wire is which I'll be good to go. I'm assuming the black wire on the bilge pumps is the negative? Then for the float switch I have 2 brown wires, one is solid brown and the other brown with silver writing on it and I'm wondering which one goes to the pump and then to the dash switch. When looking at the float switch with the wires closest to you does the left or right wire go to the pump and then to dash switch?
