I have the MB charger and cable to plug into the small port in the trunk (driver's side) but I am missing the small plug that sticks out and I need that to connect the MB cable. Anyone know the part number by chance of that little plug that protrudes from the port? I have attached pics of it, as well as what my port looks like without it.

Thanks in advance for any help, I appreciate it.

 

Well, I'll leave this post up in case it happens to someone else, but I solved the mystery. The missing piece was indeed there and not missing ... it just got pushed in and was sitting flush (that is what you see in the second pic). Of course, when I went to grab it, it fell inside the trunk and completely out of sight. Which gave me the opportunity to take the rear corner of the trunk apart to retrieve it and pull it through the hole. Good times! In actuality, the trunk disassembly wasn't bad ... took about 15 minutes.

MB charger hooked up and working!
