I want to make up a bench loom for various of my Astra's electronic.components and realise I will need to nip down to the scrappy for some connectors, but have a question.

With the advent of CAN Bus on modern Vauxhalls, did this replace the 4 k-lines used by older models for all purposes, and are all 3 CAN buses brought out onto the diagnostic connector?

I realise a look at the circuit diagrams will tell me but I'm away at the moment and can't get to that kit.

Cheers,

Ian.
