06.03.2009: 9-pin adapter
Next, you need a female 9-pin D-sub connector. You're only interested in two pins here: #2 (CAN low) and #7 (CAN high). I'm using white and green wires to match the colors of CAN low and CAN high leads on the instrumentation bus in the Saab.

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.
