Thanks @DJAlix - that's exactly what I did and it's been working perfectly. Just at the time was confused as couldn't find a single other person with the same thing. Also shoving the wires without pins into the 12 and 30 holes on the plug works, but probably not advised!12 and 30 is where they need to go. If you don’t have anything in those locations already then you don’t have anything in the car that uses extended CAN. You need to get yourself some connections pins, 009’s, terminate your wires and slot them in to the connector.
