Hi all,
I found something on this forum about the wiring for an E34 oil level sensor, but don't know if this would be the same for an E38 one (PN: 12611433510). See below:
The only info I found on the internet about the E38 wiring is something on bimmerforum but there is no source given. There they do say the following:
The pinout for the level sensor is:
Pin 1: Power from fuse 22 (switched with ignition position 2), green with white stripe.
Pin 2: Ground, brown.
Pin 3: Signal to DDE, grey with brown stripe.
If this really is true, it looks like I can't wire my E38 oil level sensor up to the C101 connector...
Anyone who could help me on this?

For anyone who finds this post, and leaves without an answer, here is what I found:
This diagram, shows that the E34 oil pan sensor, in an M50 E30 swap goes like this:
Pin 1 - Low (this is switched, so it completes the circuit when the oil level is low and turns on the check light)
Pin 2 - High
Pin 3 - GND (tie this in with the rest of the grounds)
So for my car, my High wire in the C101 was Pin 2 (blue white) and the Low wire was Pin 10 (blue violet).
So wire Pin 1 -> Pin 2
Pin 2 -> Pin 10
Pin 3 -> a ground wire somewhere.
