1989 Yamaha PRO50LF Electrical Connection?

[Powdershredder]

Can somebody tell me what this connection is for. I just completed a rebuild and am now working on th electrical and I can not figure out what this plug connection is for. Thanks.

I’m guessing it has something to do with the thermo switch? There is continuity between the two.

yellow is key on power,
black is ground/negative
pink is low oil and/or overheat

Is the plug for an audible alarm for these?

I have no idea what is suppose to plug into there, I was just saying what the wire colors are for Yamaha

Got it. Thanks.
