DS Lite volume slider to DMG Wheel slider

[tsirik]

Hey

Iam working on a project to add a dslite board into a dmg shell.

One of my wiring problems is that I want to remove the dslite volume slider and use the DMG Wheel slider that has 5 pins and not 4 like dslite volume control.

For the DMG wheel I find some wiring diagrams and I know a bit how to handle it.

For dslite board can’t identify what happent ....
This slider doesn’t have ground connection the top right and left pins are Connected and I don’t know where is the vin and vout to handle the 2 speakers.

Is anyone that know or can imagine the wiring here ?
