Hi there,

Does anyone have M50B25 and M52B25 engine wiring diagrams for the X20 connector? The sticky images seem to be down.

I am putting a 1991 M50B25 auto engine (with manual box) into my 1998 323i (M52B25) and need to see the wiring differences.

Thanks!

Cheers for that.

The M52B25 323i has EWS, but the 1991 M50B25 doesn't - so I don't think I will have a problem with EWS? Also the M50 loom is running VEMS, so no EWS anyway!

Been looking through the electrical troubleshooting manuals for the M52 and M50 and it seems that the X20 pins are are same for both cars, so I don't see why I would have an wiring problems?

Been getting conflicting information from various sources...
