Help required please - I Need to Locate the CAN BUS inside the Cabin of a R170 Face Lift (2001).

I know I can go to the engine compartment and connect to one of the Black Box's there.
But I would then need to go through the Bulkhead to get it to the cab - Plus a long run of wire to get it where I want it.

Would it be OK to connect to the under-dash socket with a V splitter cable so the garage can still do a diagnosis.
Also would I have to put a terminating resistor across the twisted pair wires I would end up with.

On the 98 model there are two buses, engine and interior, which devices do you need to snoop/intercept?

Z37/2 and Z37/3 are engine CAN lo and hi connector sleeves under the passenger carpet and equipment bridge.

On a 98 at least, you probably want the bus between the PSU and MFCU then - but that bus doesn't stop inside the cabin AFAIK. You could try the above engine bus but you may not see the messages you need to see.
