Questions about "vintage" Yamaha Gauges

I recently purchased A pontoon boat with the intention of restoring it. The boat is powered by a 2 stroke 90hp Yamaha outboard along with having Yamaha gauges and controls.
My question is: I have 1- 2" round gauge that is missing the lens and face. It has what looks like 3 LED's in a horizontal row. The gauge has 5 wires on it 1-Green, 1- Green w/red stripe, 1-yellow, 1- Black and 1-Pink.
I would like to know what the gauge is for and if it possible to buy a NOS gauge?

It's the oil level indicator and is no longer available.

Well at least I know what it was.
If anyone has one laying around or knows where I can get my hands on one, I would appreciate it.
Let me know.

Thanks for the info.
