XK8 Electrical System Architecture
The XK8 system "architecture" features vehicle multiplexing. Multiplexing allows for greatly simplified wiring harnesses, while at the same time allowing flexibility in programing market variants. Two data networks are used in the system: a controller area network (CAN) for the engine, drive train and related systems, and a standard corporate protocol network (SCP) for the body systems. Any vehicle subsystem depicted on the figures with the CAN or SCP included uses data derived from the network, or transmits data via the network to achieve control. Messages for both networks are listed in CAN/SCP Network Description and Operation
In addition to the two networks, the XK8 uses a serial data bus (ISO) for diagnostics and for the programming of certain control modules.

The XK8 uses both power and logic grounds; however, it does not use a common logic ground stud connection as in previous Sedan vehicles.
