Did open up the properties last night and it says the device is working properly. I used some long nose pliers to snap the pin off, I think it snapped off at the base, I'll double check when I get home.
The pin is snapped off flush with the plastic.
Bought another Mongoose cable with the same issue but the pins were numbered, so managed to snip off pin 13. Plugged it in to the car but now SDD wont even give the option of reading the cars VIN. Just stats that there need to be a BSU connected...
