What type of tip is at the end? What guage is the wire? As to the bilge pump: There should be three wires to the float switch. One is the live wire from the battery, main breaker, bussbar, or battery switch. This gives the pump electricity even if the battery switch is off so that any water which gets into the bilge while you're away will be pumped out. One wire goes to the bilge pump switch on the dash so you can manually turn on the pump whenever you want. The third wire is a ground wire to complete the circuit. The "always live" wire (probably brown) and one of the wires fron the float switch connect to the pump. The other wire from the float switch connects to the other live wire (probably black). The ground wire connects to the other lead of the pump. The only tricky part is connecting the wires to the correct leads on the pump. if you're wrong, the pump will spin but not pump - it'll be going the wrong way. Then just switch leads. The float switch wires don't matter; either way will work. Hy
Green wires on boats are most often a ground wire for thru-hull fittings, etc. Not a 12V ground, but they usually go to the ground buss bars shared with 12V grounds.
