I used the unused second thermocouple-sensor cable to connect the sensor. Regarding wiring: my sensor came with brown (+) / black (sig) / blue (-) cables.
My wiring:
Sensor to Thermopile cable: brown to brown / black to green / blue to orange
at the UM PCB: brown to ground (left pin of the TC input when seen from the side with the PCB upside down like it's normally mounted) / green to the Z-min input (right pin) / orange to +5v (middle pin of the TC input)
