Please identify this Switch

[Downloader]

Hello everybody.

I got my 2004 Aquasport 215 Osprey a couple of months ago and now in the process of replace some lights, installing VHF radio and general maintenance of the wiring I found this switch under the gunnel, it says courtesy lights but I have a switch in the helm panel for that, can someone identify this switch, it's purpose and the 3 cables that you can see in the picture?
 


Thanks in advance!!

It could actually be for the courtesy light - maybe it was multi color with one common and a hot to each color?
