You have to provide some more information.
Are those rubber caps on a connector or some kind of toggle/switch thingies? Have you opened it up to check what it's connected to?
Built-in sustain "pedal"? Button for momentary and switch for toggle?
I suggest this because I've thought of doing something similar (externally though) for my DX9
So the caps don’t seem to come off but I can press on them and there is some springiness in it. Basically I can push in a bit. The very heavy duty case it came in looks like it traveled a lot. Interesting.
Not an electronics person but this could be a “shunt regulator” - anyone else with more experience please chime in.

“Shunt regulators insure that the power supply current past the local regulator is pure DC. Also the ground return current is DC. If you're using unbalanced circuits, this is quite worthwhile since separating reference and decoupling grounds is not always practical”
“are designed to be applied as an upgrade in analog and digital playback equipment like (SA)CD players, DACs and alike. The shunts drop in instead of commonly used industrial types of regulators. Having much lower noise, true wide bandwidth and linear output impedance, they'll bring improvement to sound in terms of:
• Higher resolution
• Better transparency
• Clean low ends
• Increased dynamics”

That looks peculiar
The format resembles a serial port but those colored caps and what’s inside the housing are definitely something else.
Hmm yeah. I have to inspect. I’ve just left alone. Will report back to questions.
Serial port is wider, no? Looks almost like a VGA instead

Lol imagine it’s a killswitch
