X164 -GL 450 How to determine missing parts?
 

Hello,

Can someone help me possibly identify one or more missing parts?

My SUV was broken into and some parts were stolen from it.

I'd lost control of the following after the theft.
Liftgate .
AC.
Lights
Park sense - parktronic.
Gas Gauge.
and some other minor functions.

I researched it and realized it was at a minimum a missing SAM, which I replaced - specifically MB part # A16415401101/Delphi 28064105.

After this I gained some functions back, but not all.

As of now, AC still blows hot air, and while the gas gauge is no longer showing the warning light, it's still showing empty even though the tank is full.

From the attached pictures can you tell which part(s) are missing?
There's a loose plug connector (circled) that I can't seem to find it's receptacle.

I've spoken to my local MB dealer, but they can't seem to , or aren't willing to identify the missing parts from the picture.
The car is not easily accessible, so I can't take it to a dealer.
