Question M272 E35 on W219 CLS350 help identify wiring




Hello. Yes I bought a lego W219 CLS350 without an engine. Bought an engine from W221, rebuilt it. Put into chassis and now i have two "unused" plugs.
1. PHOTO 1. Marked with small arrows. Wire comes in a loom with wires for sensors on the left(driver's) head. Wires goes behind the black hydraulic reservoir and somewhere below. Ive seen that on photos. But my wire is just flying around and i cant find where i can plug it. Anyone know where and what is it for?
2. PHOTO 2. This is harder. I havent my own photo so i am showing from the internet. Wire comes out from the central loom (where i made a circle). Everyone around doesnt have it, but does have a wire in a rubber that goes to the thermostat. But my termostat is plugged somewhere from the bottom. And on top from the loom i have a wire in a plastic not rubber housing that just flying around and can reach belt/pulleys. Plug has 2 contacts but only one is used (one wire inside)

Maybe someone has an engine lying around or maybe you are very good at these. please help!

I have the same two wires! Basically, one of them comes from the main harness, goes into the thermostat, then into nothing. And the second one on the PS pump side, I have one that doesn't go anywhere then the one at the end goes in the AC compressor.
I have made a little diagram so you can see.

Digoec: I think that your AC problem comes from the last wire not plugged in.
