Thanks a lot, good thread. However, I am not that advanced yet in electronics, so I would like to check, if I can wire it like shown below? Or do I have to buy the OSH Park board?

almost finished wiring of my Flashforge Creator Pro 2016. I am struggling with the Heat bed temp Sensor. I thought it was a thermistor, but there are 4pin connectors. On the bed, it says +3,3, GND and SIG (see picture) Where are the cables going in the duet? Can you give me a hint? Thanks a lot.
