C5 RS6 ECU Pinouts/Diagrams?!

Post by jolio1994 » Tue Mar 10, 2020 7:17 am

Currently finishing up my BCY swap into my '95 S6 Avant. I've found a few pinout diagrams for the ECU here and there, but haven't been ale to find anything solid...

Does anybody have the Pinout's for the ME7.1.1 ECU aswell as the connectors that plugin from the engine loom into the chassis harness?

Gracias :jump:

Joel,

I have some of this info. I thought I had emailed it to you before, but I just did again.

You’ll need to be able to read track diagrams

I've been slaving over it Andre, thanks for the diagrams.

I've managed to narrow down the necessities of what's need down to the OBD2, drive by wire, fuel pump/injectors, and terminal 15/30 + grounds.

Tomorrow I'll cut everything else I don't need and finish the in car harness. Again, big thanks! The one really unknown I had was where VSS goes in from. It doesnt look like the ECU even see's VSS unless it's from the CANBUS or another undisclosed location (which I cant find)

From what I remember, the VSS goes from the sensor directly to the cluster, and then out to the ecu. Email me back. I pinned out the plenum harness for an 02 s6 a while back when I did my 2.7 swap and a lot of the basic stuff should carry over.
