Hi there, most (as in almost all) of us are US spec members and will do our best to help you out. I have no idea how to help you though.
Are you adding a towbar to the rear or the front. For the rear it should just bolt in.
I am guessing you are asking about the wiring for the towbar?

the can bus is a very sophisticated communication system for the car. it allows the modules to talk to each other and share info (rpm, temp, speed......). im not sure how having a tow bar would require access to the system. if you are towing the car and you are looking to have the signals work a simple pig tail that ties directly into the wiring harness for the lights would work. if you are trying to tow with your car and you want lights for a trailer or to have trailer brakes then yes you would want to slave in a relay into the harness. this will protect the cars electronics from high amperage draw. this should be done at the power distribution box under the hood and not at the rear of the car.
