I'm not an electrical engineer but the resistance of the heatbed should be around 5 ohms plus maybe one ohm in the cable to err on the high side. Making a detection circuit that can reliably differentiate between 6 ohms and 1 is probably pretty hard.
I'm trying to find the connector but it doesn't seem to be documented and google is turning up nothing. I measured the pitch on my printer but couldn't make it out perfectly without disassembling the bed. It looks like it should be 3.5mm. Could you measure on your bed?
Cheers

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

That is some seriously scary shit right there.
