Hey Mike, thanks for reaching out!
Sounds like you're needing the 7-Way to 4-Way/5-Way Trailer Adapter # C35FR to match the 7-Way on your 2018 Porsche Cayenne with the 4-Way/5-Way on your EZ Loader boat trailer.
This adapter was designed for pretty specific applications and your vehicle falls into the category of having Lamp-Out Sensors and the boat trailer having LED lights so the adapter will work out perfectly for you!

Hey Mike, how did things go with the 7-way to 4/5-way adapter on your Cayenne and EZ Loader trailer? It’d be great to hear if the LED lights worked smoothly with that setup. Your update could make it easier for the next person with the same combo.
