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

That is some seriously scary shit right there.
