If you really want to, you could disconnect your battery (s) unscrew
the switch from panel, look at the colour of wires and trace them back
visually under sink area. You should be able to find them there. If
not, they may be run to the LH side in which case you could take the
LED panel off and see if they're there and visually trace.

Just a thought.
