Pontoon Boat & Deck Boat Forum

Hello,
We are redoing a 2000 Suncruiser Trinidad pontoon boat for some friends. Starting in on the electrical we have traced what 3 of the four toggle switches on the console operates, but can't figure out what the third toggle operates. First are the Nav lights, second is the live well, third we can't figure out and forth is the horn and it's a tan color switch where the rest are black. Any help you could give us would be appreciated. Thank You!

Maybe just the white anchor light on top without having the front nav lights on. Just a guess.

Cockpit or playpen lighting?

Docking lights? (Maybe the lights were removed at some point in the boat's life.)
