Yes it's true, you can as this product Bestseller Nr. 1 designate. It fully met its purpose and connection adapter. The adapter is turned on it in a 90 degree rotation to the existing 13-pole connection socket, I use the adapter only when the trailer must be connected. Quick attach u Aufmontage. Why buy so expensive when you get the product delivered to a Schnäpchenpreis. Very good quality processing.
