Hello everybody, first time posting on this forum. Just picked up my 16 Gla 4matic a month ago or so and I'm already doing mods to it. So far I have the peal commander and the Curt Hitch now I just finished installing the Curt Wiring Harness and I will be posting some pictures of how I did it. I am sure there are several different ways of doing this but I did it my way and I'm sure it's not the best but I does work and it looks clean. I will be adding some pics shortly.
