I'm trying to access the CAN bus on a 720S to retrieve basic vehicle parameters (throttle, rpm, gear, etc).

On other McLarens I've been able to use pins 1 & 9, but I've been told there is no high-speed CAN data on the OBD port and believe i need to use the development socket.

I think i found the development socket (long, white rectangular connector behind an access panel behind the driver's seat), but can't see any twisted pairs.

Can anyone advise, please?
