Got my second hand BCM this morning, so I immediately hooked-it-up to the test jig (see below). It looks like a spaghetti bowl of wires, but they all make sense with the help of a bit of logic and a lot of luck! I'm very lucky to have found that the same jumper-wires that I use on Arduino circuits fit many of the pins on these controllers!
What's even more amazing is that the set-up actually works!!
I can poll the BCM with VCDS and VCP (OBD11 gets a bit cranky when it doesn't see a VIN in the polling process). I can talk to the BCM (via the CAN gateway) and it talks back in the correct language. Got lot's of DTC as you can imagine with no lamps connected, and no external equipment sending back the correct signals. But this doesn't matter for my purpose!!
