Parts Needed to Install 7-Way and Curt Echo Mobile Brake Controller 2012 BMW X5

Question:

Quick Question so I make sure I buy the right items from you. Primary Vehicle 2012 BMW X5 3.5d • I already have the Curt 13077 Class 3 Trailer Hitch installed • I’ve been using it to attach a bicycle carrier, but now am wanting to hook up a car trailer • I think I need the following parts from you o Item #119190KIT to attach to vehicle wires to get a 4 pin harness o Item #37185 to turn 4 pin harness into 7 pole connector o Item #C51180 Curt Echo Wireless Brake Controller I’d like to use the wireless brake controller so that I can also use it with my 2012 Winnebago Mercedes Sprinter based RV. The RV already has a 7 pole connector but does not have a brake controller from the factory, and no easy way to add one hence the desire for the wireless one Will this work?

You're very close but the 7-way adapter kit you'd want instead of the 37185 is the part # ETBC7L which comes with the additional components needed to complete the 12 volt accessory circuit which the Curt Echo part # C51180 needs to operate. The # 119190KIT is the correct 4-way kit you'd need as well.
