Schematics of a Sanguinololu board can be found with google.
The main thing is you have to do some soldering on the board to make the 3wire connector on the board accept a 3 wire optoelelectric endstop. But it can be done and it works.
Before proceeding: do you know if the endstop is designed for 5V or 12V?

Hi,

this would be a possible layout for such an endstop. Note that the ordering of the contacts is different from the one on the K8200/3drag controller (±S vs. S±). Also, the printer may have problems when operated in a room with (too much) sunlight.

Cheers,
