M52 wiring harness picture/diagram?

[Leo_328i]

Hey guys,

I just picked up an M52 motor and am in the process of labeling all the connectors for what they're for.

Surely someone has done this and labeled it, taken a picture or put together a diagram! Anyone know one?

I've googled around for the last half hour and can't seem to find anything.

Cheers guys.

Continuity test is the best for sure method imo. The only ones that are not easy to identify are the cluster of plugs right under the intake. Spread out the harness and take a pic. Put labels on the picture if you can and we will be able to knock out some of them. Some can't be done that way though. Your gojing to have to do some work.
