the curt hitch is very nice..
the oem bimmer wiring harness is more then the hitch..
Nothing to modifie... bolted right up.. no problems..
that pic doesnt really do justice....
since i have the cold weather package.. i think that the rear bumber was a little different them some of yours.. i might hack up that little cover that comes off for the hitch to see if i can better fit it..
the only thing is that the curt hitch does NOT come with the little side mount for the wireing.. I will figure something out later thats better looking... but for now.. i wanted to go home.. it was 90 degree and i was tired..
