Porsche 996 DME Pinouts and Connectors

[Dwiggy]

Looking for the connectors and DME pinouts for the Motronic 5.2, 7.2 and 7.8.

Thanks,

D.

They are different for each model.

You will need the DME OBD II service manual for each.

Thanks Loren.

Does anyone have the DME OBD II service manual for 5.2.2 996? If so can you scan in the pinouts or pm me?

Thanks,

D.

I believe this is the DME 5.2.2 can anyone confirm because pin 58 has me a little confused.
