Connect the BDM to the parallel port of your computer. Attach the ribbon cable to the ECU, making sure the polarity is correct. The ECU needs to be powered up, see this guide for DC power harness information.

Here's a brief guide on how to connect a BDM interface to a Trionic7 ECU.

BDM (stands for Background Debug Mode) is an electronic interface for debugging microcontrollers and other embedded systems. It allows direct access to circuit components. In our case, we will be using it to overwrite the flash memory on the Trionic ECU. Normally, connecting via the CAN bus is a more convenient way to flash it, but if that process fails, you end up with a dead ECU. The only way to revive it is by attaching a BDM controller. Guess what happened to me ;].
