[jl277013]

Trying to follow the letter of the law now to wire the harness and control module for a 2015 X3. It appears that BMW changed the parts for 2014+ and the 82712157704 kit is no longer valid. The actual mechanical parts (all except the wiring harness and control module) appear to be right, so buying the kit was not a waste as the individual parts would have been more for a 2015. The wiring harness is fairly close to the 82712157704 kit, but is it not exactly the same. The control module (pictured) accounts for the primary difference. The module has 4 ports A, B, C & D; however, the harness only has terminals for A, B & C as shown. It appears that the modules in the battery compartment sometimes do not always use all ports, but sometimes there are hidden terminals wrapped with other cables (I could not find one in the proximity).

Can anyone tell me what the D-port is?
