Blind spot radar inoperative

 Please if anyone have had a same problem

I own 2011 ML 350 bluetec, and among all other problems this one has taken lot of my time, money and nerve.Long story short, after loosing radar operational use and getting short circuit,loosing ability to shift into gears with all the warning lights coming on the dash,I finnaly got me sensors but what a surprise, they don't  work. Apparently there is no power on the conectors. Fuse is OK, and the diag is saying the problem is in X29/35 BLIND SPOT RADAR MONITORING ELECTRICAL CONECTOR.If anybody knows the what are those conectors and where are they located because on the wiring diagram O don't see it 

I appreciate any help
