I just received my trailer hitch and am looking for a good deal on the wiring loom. I know how to install and its so easy a caveman could do it. My question/concern is that it will throw a code do to the finicky CANbus system and I'll have to visit the stealership to have the tow "software" activated. Can anyone who has added the tow wiring shed some light on this topic? I only plan on occasionally towing small trailers and I have towed before. Thanks in advance.
