Can anyone positively identify the CAN 1 & 2 wires in this photo?
Furthermore, looking at the diagram I see no CAN lines at the PCM.
Pin diagram from top of PCM
Wiring diagram of Boxster but I don't know what model year.
My PCM is equipped with NAV, Bose, no sport chrono.
I believe the two orange cables are fiber optic which speakers are linked.
Does anyone have a wiring diagram for a 2005 Boxster?
My PCM has a digital clock display. My instrument panel also has a digital clock display. They seem to be in sync so they must be electronically linked. Doesn't that mean there has to be wires running between the two and if so, are they not the CAN high and low?? (Which means at least two of the wires in the pic have to be them?)

If the other changes concurrently with the other one then I'd say they are indeed linked.
And by CAN could certainly be possible. But without a wiring diagram it is hard to know which lines are CAN. If the car is on and the CAN bus active the lines would be electrically active but I have never bothered to use a volt/ohm meter to "look" at the CAN lines/signals.
CAN is a differential bus and I believe the voltage levels on both lines would read around +5V but like I said I've never used a volt/ohm meter to look at CAN signals. I used an analog or digital logic scope so I could see the line signal pulses and I was using a relative inexpensive CAN bus simulator not a real car's CAN bus. The only thing I plugged into the car's CAN bus was a CAN bus snooper, Vehicle Spy.
You have to be very very careful. Static discharge into a CAN line and you could blow some expensive processors.
