My assumption would be that W.W. Williams changed the ECU programming from a pre-98 series 60 to programming for an 8V92. I would try plugging your VMSpec dongle into a DDEC port in the engine compartment. CANbus isn't rocket science, you have a positive, negative, CANbus high, and CANbus low that will feed all the information to your VMSpec.
If your engine compartment DDEC port works, you will only need to run a twisted pair for the CAN high and CAN low to get your driver's compartment DDEC port to work. You already have the positive and negative connection, just missing the communication. Pin-outs are easily found with an internet search.
