My recommendation is buy a new lighted 6 or 8 switch panel. Cut a hole right where the switches are now & mount it there. Replace any questionable wire with MARINE GRADE wire. Don't skimp!
NAV&Anchor/off/Anchor (I'm assuming you have an AllAround white light.)
Horn (momentary ON) get a red switch cover for that one
Bilge1ON(manual)/off(both will be Auto)/Bilge2ON(manual) (wire them both AUTO to electronic sensor switches to the battery with in line fuses)
Wiper on/off
Deck lights on/off
Electronics On/off ( you want to be able to switch off the power to FF/GPS/VHF cables to prevent corrosion, ask me how I know...)
The Compass was probably originally connected to the Engine Key On power. If not, connect it to your Anchor light.
You didn't mention Fuel Gauge. They usually came with a momentary switch but an on/off is better for when you're by yourself...
SO...
The new question is "How is 12V power fed TO your switches?"
Do you have separate 12V feeds from battery, thru an inline fuse, to each switch or is there a fuse block fed by a heavy (8 gauge) wire from the battery?
Is the main feed fused at the battery?
