ECS:

No, the OP needs the trailer wiring kit. Your number for it is 185391, for $157.49. You currently show it on back order.

Perhaps you could answer a question though. That part above shows the white wiring module that plugs in to the vehicle, as part of the kit, in the photo here: BMW E53 X5 N62 4.4l > Exterior > Trailer > ES#185391 Wiring Harness - 71600009698

However, the description there says that the Siemens module is required as well. Then you list 169157 as the plug in module by itself, for $144.53. Are both in fact required, or does the first kit include the module as shown in the photo? Over $300 for the wiring kit seems pretty high, given your full hitch kit price of $429.17 includes all of the wiring kit as well as the hitch.
