Anyone has a link to wiring diagrams or technical info / test procedure / troubleshooting manual about the EDC plus system. This was used on E34 M5 3.8.
Found out that some E32 Alpina B12 5.0 also have this system. I gave my spare EDC III control module to by buddy but he found out that he has this EDC plus module.
For the EDC plus for the M5 the part number of the module is 37.15-1 139 600 12V 412.215/071/001
