Hi All,

I am trying to use this newly bought BDM100 Clone, but nothing seems to make sense.

Please find attached a picture of the PCB board and the marrelli head.
Ground on ME9.7 ECU is shown in the pic, 2nd from the right on the outer row. But the ground on the marrelli head is on the other side (where pin 5 is). have I missed something here ?

- Also, do I need to use an external power source?

Help appreciated!
