Preferred Way to Route Power Wire for Trailer Light Harness on 2013 Porsche Cayenne
Question:
Do you have a link for the wire harness install on the Cayenne? I was looking for the preferred way to connect the wire to the battery and run it through the cabin since it’s not in the rear of the vehicle like the Audi. Thank you.

We haven't had the opportunity to install the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT on a 2013 Porsche Cayenne as of yet (August 2023), but I do have an install video on a 2017 Cayenne to help you.
Basically, what you want to do is route the wire underneath your vehicle and avoid any moving parts or places where it will get really hot. It's a good rule of thumb to follow the brake lines because these are already routed in this manner. You can run it through the cabin if you wish but we prefer going under the car because it's easier to hide, and you won't have to find a way through the firewall at the front of your vehicle.
Attached is a link to a helpful article on routing the power wire that goes into a little more detail.
Since you are installing wiring that tells me that you plan on towing. If you don't already have a trailer hitch then I recommend the Draw-Tite # 75950 for your 2013 Porsche Cayenne which has a hidden crosstube and a nice mounting bracket that you can pair with the bracket # 18144 for an easy mounting point for the 4-Way.
To complete your towing setup you also need a ball mount like what comes in the Ball Mount Kit # 989900. This kit includes two ball mounts, one with a 3/4” rise/2” drop and the other with a 2-3/4” rise/4” drop, a 1-7/8” hitch ball, a 2” hitch ball, and a pin and clip. You will want to refer to the attached ball mount article to ensure that this kit is correct for your towing application.
