I'm trying to figure out the benefits of using an OEM towbar (trailer hitch) wiring kit vs. making my own for a B5 A4.

I believe the OEM towbar wiring kit is made by Westfalia, but thier site and manual don't seem to have much detailed information about the function of the wiring kit.

buddyracing - is your OEM wiring a 7 pin or 13 pin euro plug? Do you notice anything different in displays or notifications on the dash when your trailer is attached? When a bulb goes out, how are you notified?

Thanks - Chris

Pep boys had a kit that I used in my car. It was something like this one.
