What is this? Where does it go?
 

Hello I'm new to the forum and not overly familiar with Mercedes. This really should have went to a dealer but I told a friend we (my shop) would help him out. He has run the car with flats on the passenger side until the tread came off and tore the inner fenders completely out of the car plus some other cosmetic damages. I have no idea why and I do not want to know why this was done. In the RIGHT REAR fender well is a section of wiring that is missing. I have not been able to find where it went or what it goes too and thought some one here could help me.

Figured it out. This wiring harness goes to the vacuum canister located in the front of the right rear fender well. New harness ordered and we're on our way.
