Hi all,

I'm about to start transplanting a S50 ('95 OBD1 M3 motor) into my '92 525i. My car doesn't have Vanos; the new motor does. I have the ECU for the motor, wiring harness from the donor, etc - but I'm not certain of a pinout for the M3. Can anyone help with a wiring diagram for the motor? Will I need to tweak anything for my instrument cluster? The donor motor came from an automatic car; mine is a 5speed - I recall that the transmission interacts with the ECU for the new generation. Is my memory accurate - or do I need to perform additional alterations?

Thanks for any assistance y'all can provide.
