Picked up a seized engine E70 (N55)

[A/C]

I hope I can resurrect this post, if only for my selfish reasons…
Anyway, I too have an x5 e70 n55 and just finished rebuilding it.
The engine is already in the bay and hooked up, except for three connectors.

1. I can’t seem to find where the oil pan level sensor connector is hiding.
I looked everywhere and it just vanished into thin air.
Any ideas where to look for it?

2. Finally, I have two connectors that I have no clue where to connect them to: the tiny one is on the same wire as is the a/c compressor and the larger one comes out of the module right beneath the air intake.
I attach a pic for recognition.

Anyone could point me in the right direction would be greatly appreciated!!!

Also, I do have some photos and suggestions of mine in case anyone is/was up to the challenge to remove their n55 and wants more insight.

Thanks in advance!!!!
