Is There a Trailer Wiring Harness Compatible with the 2018 VW Tiguan 4Motion?

Expert Reply:

There is not a custom fit at this time for your 2018 VW Tiguan with 4Motion. The custom fit harnesses from our manufacturers exclude the 4Motion. Because there is not a custom fit, your best option is to use the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. This kit will not splice into your wires but instead will use the zero contact interface sensors to capture the needed signals. The module will draw power directly from the vehicle battery to protect the vehicle electronics.

I've attached a couple of videos to assist.
