This is probably a really dumb question, but I have recently purchased a 2008 Cayenne S. It has the factory trailer hitch installed. However, I cannot seem to locate any wiring for the trailer. Is this located somewhere not readily visible, or was the trailer wiring a separate option not included with the factory hitch?

Thanks,

The wiring should be there, tucked away in the trunk storage on the right. You may need to do to a dealership to get it plugged in properly.

 

Is there a plug holder with blank plate next to the hitch? It would be tucked up under the bumper. If so, you have to remove the plate and install a plug adapter.
See this thread for required parts. This was for my 2006, but I believe it should apply to a 2008.

If there is no connector blank plate & plug holder, I am not sure what your options are, I believe the factory tow package was complete except for the plug adapter (& a brake controller).
If this is not the case, I got nothing
Proceed as asp13 suggested.

 

You hit the nail on the head. There is a "box" mounted up under the rear bumper next to the hitch with a cover plate on it. I figured it had to be the trailer connection, but have to admit I expected Porsche to provide a plug and wiring although probably without the trailer end. Thanks for the link to the Rennlist thread!
