Hello everyone, i need a bit of help.
I am currently working on another euro swap here in the US this time with a S50B30. I want to know what is the difference between the b30 wiring harness and b32? I have a spare LHD harness from my b32 and wondering if that could be salvaged to use on the b30. i do have a proper b30 dme coming as we speak.
From what i can find they have different part numbers
S50b30

S50b32

Any help would be appreciated,
Thanks!
Could probably contact Alex L. xyobgyn@aol.com pretty much one of the most knowledgeable guy on the "euro" or rest of the world motors.

The B30 also has a TDC sensor (on the vanos bridge) the B32 hasn’t.
And for the B32 there is the SMG version, where there is a separate control unit for the SMG and the extra wiring going to the shift solenoids, pumpmotor, pressure sensor.
And of course the wiring for the 2 extra vanos solenoids for the exhaust side.

The 3 liter S50 harness has a separate VANOS connector. On the 3.2 liter the VANOS is built into the main ECU so it has only one connector. Coils and injector connectors are all the same otherwise.
