Towing-Electrical Connection

Electrical and Electronic

Vehicle Information: Model : Cayenne S; Year: 2003; Mileage: 0;

I am interested in purchasing a Cayenne for general use plus towing 6-8 times per year. I saw a Turbo at a local auto show that had the trailer hitch option. It had an electrical connection next to the hitch receiver. Is this only for the trailer lights or is it also a connection point for electrical trailer brakes? If not, what will be involved in making electrical brake connections? On the BMW X5, this is a major item, requiring 7-8 hours for a good technician who has done it before. I gather this is because of the electronic bus technology they use. I apologize for asking such a detailed question so early in the life of the Cayenne, but I am hoping you will have a Porsche contact that may be able to help. Thanks!
