06.03.2009: In-car connection
Connect your green "CAN high" wire to pin #33 on the ACC harness, and your white "CAN low" wire to pin #34. Turn the ignition key, and enjoy a live connection to your ECU. P.S. Perhaps it's time to clean the screen on my laptop ;]

Here's a brief guide on how to connect to the CAN bus on a Trionic7 ECU.

CAN bus connection offers a fast and convenient way to read or flash the firmware in the ECU. However, keep in mind that there's a slight chance it may fail while writing the memory, especially if you're flashing in the car. When that happens, you end up with a dead ECU, which no longer responds to a CAN connection. The only way to revive it in this case is by using a BDM interface.
