Tow hitch wiring DIY?
Does anyone have directions for installing the OEM tow hitch wiring? Locations for where to find the plugs, etc?
Also, does anyone know if Porsche will sell the wiring harness separate from the hitch itself? I would prefer to use an Execuhitch rather than the stock mechanicals, but I want to use the trailer brake controller wiring and also get access to the computer changes that happen when a trailer is plugged in (stops the trunk opening, etc.)
