Help with wiring 7 way trailer light connector

I can’t find any plug and play t-harnesses for the 16 cayenne. Has anyone wired a 7 way trailer lighting kit with success? What one and how did you do so. Thanks

I gotta ask, have you removed the cover on the Porsche connector car side? Porsche sells the car side for less than 40. If so and your asking for the trailer side any 7 way works.

Check over on Rennlist. I know folks are doing this. Did the Cayenne come with the hitch and harness or are you adding it? I remember reading that the VW Toureg parts fit and cost less but you will still need the PCM coded for trailer us IIRC.

If you have the factory installed trailer hitch, you will find a square, plastic cover with a screw in each corner to the left of the hitch. Remove the cover (first the 4 screws, then the latch holding the cover to the socket) and you will find a European 7 pin socket. Your dealer or a VW dealer or online at a place like Suncoast or etrailer.com will sell you a Pollak Replacement 7-Pole, RV-Style Trailer Connector Socket - Vehicle End - PK11893 which will plug into the European connector and screw right where the cover was with the same screws. This will give you a covered, standard 7 pin trailer connection. If you need to connect a 4 pin trailer connector to it, get an adapter to go from 7 to 4 pins like a 7-Way to 5-Way/4-Way Trailer Adapter for Vehicles with Lamp-Out Sensors Towing Trailers with LEDs. If your trailer uses LEDs it can play havoc with your Cayenne's lamp-out sensor so I recommend getting an adapter that can handle the LEDs even if your current trailer doesn't have them.
