Thanks, despite having 216,777 miles on it, yes I suppose it is quite rot free.
Doesn't normally stand still long enough to rot!
Not really an expert, but having access to Vauxhall's TIS wiring diagrams does help ( but only cars from 1998 onward, so the Cavalier isn't covered).
I understand what CAN is, and how it works, but that's as far as I go.
I believe that there are two or three types of CAN...which are: -
1) For standard cars
2) For trucks and Lorries and
3) Mechatronics CAN used in industry
In lay-man's terms it is a digital data-stream that runs between 2.5 volts (Reference line) and 5 volts (signal line).
There are three speeds
Hi-Speed CAN, (2 wire pair). CAN on other makes
Mid-Speed CAN, (2 wire pair). LAN on other makes
Lo-Speed CAN, (Single wire). VAN on other makes
My use of CAN, is to gather the necessary modules from a 2003 Vectra-C, and then link them via my Radio Display Screen.
As an example,
My screen has 32 wires in it, but I only used about 10 to get it to work.
My Radio head-unit has 40, but I only use 18
My BCM (Body Control Module) has 78 wires in it, but I only needed about 12.
My CIM (Collumn Integrated module) has a 32 pin plug, but I only used 5
Sadly, it gets a bit expensive getting these modules and the next item would need to be an Engine ECU, and possibly an ABS ECU.
The Engine ECU has 102 connections, but I would only need about 12 and finally the ABS module has about 20 connectors, but I would only use about 6
The tricky bit is squeezing all this in the space behind my glove box, without generating too much E.M.I (electrical interference).

Great news
Thanks for nice appraisal,
Thankfully, pictures at this low-resolution can be quite forgiving and so hide a lot of the minor imperfections.
Of which there are many
