Oil pan to Driver's side frame rail
Those are the major ones, then in the car, there is a main one under the steering column. For details you'll need to get an ETM.
On the older ETAs and cars with rubber alternator bushings there is also a ground strap from teh alternator to the engine block.

NO ECU is grounded threw the engine harness to the block by the Diagnostic connector like stated. ETM is the factory Electrical trouble shooting manual, search on ebay or go into to your dealership to get a copy. It has wiring diagrams for every system along with where grounds and connectors are located.85 325e 2.7 ITB'd stroker

The alternator ground is attached to the block.
Check the Bentley if you don't beleive me, they are all listed there.

Originally posted by rs4pro3I know, just stating it differently, it's grounded at the Diagnostic connector threw the intake manifold, to the block, then threw the block to the oil pan, then to the chassis frame rail.
Fucking internet, so easy to misread people.
