Hi - I am towing a 20 foot travel trailer with an 04 Cayenne S. When plugging the trailer into the vehicle or brake controller, the lights on the trailer flash continually. I plugged it into another vehicle and the lights and controller work fine. This leads me to believe there is an issue with the trailer wiring on my vehicle. The vehicle does have factory towing - so I'm not sure what's causing the issue.

Any help would be great!

LED railer lights frequently cause that. There are adapter plugs that cure the problem.
