There are two wires connected to the float switch.

I've never wired anything on a boat before so excuse my ignorance.

I know one is hot and one is ground, I can probably figure out which one is which. But now, where does the ground go and where does the hot go, also seeing that this thing will be in water, I need a great splice job to make sure I don't wet the area where I am connecting the extention wires.

I hope this make sense.

ps. I don't want the flow switch to work with the ignition, so does that mean I wire it directly to the battery?
