Looks like just power to one or two leds and two sensors.

I think the sensors for A and B quadrature are on the ends of pic 3. ends of the bottom LHS set of pads on Pic 3, or pins 3 & 5 (numbered from the top) on the 5 RHS pads. I don't understand the middle pads.

Something a bit like

Exactly! and based on the number of pins, the grounds are common.
