I have an aftermarket towbar, non detachable, with wire harness to deactivate parking sensors automatically. Works just fine!I also got the Westfalia one fitted, but I am dissapointed that it did not come with a cover to fit over the hole in the bumper when the tow bar is removed. Another annoyance is that the rear parking sensors are not deactivated when a trailer is attached. I contacted Westfalia and they told me that they did supply a connector that would disable the parking sensors when a trailer was hooked up and therefor I wonder if my dealer screwed up when installing the tow bar. Does your set up disable the parking sensors?
Also could someone with the factory tow bar check if there is a part number on the back side of the cover that came with the Mopar tow bar? I'm hoping that maybe the Mopar cover also can be used to cover the hole from the Westfalia aftermarket one.
