Speedo plug identification

This plug I believe is coming off the speedo. Anyone know where this connects to? Boat is a 92 Nitro 2000 DC.

Most speedometers that I have seen run off water pressure to give the reading on speed. That looks like a socket for a light bulb for the speedo light.

 

[200mph]

+1 on light

That’s one of your gauge lights with the bulb missing
