I'm about to install a trailer hitch on my 1999 Avant. I have not been able to find a snap-in "T" connector for the trailer lights soI'll have tocut into the existingwiring. Anyone knowwhereI can find a wiring diagram/schematic for this car?

Thanks in advance

 

I have a Chilton's manual for my '98 A4 - it has wiring diagrams for the entirevehicle in the back. The A6 manual surely has the same section. I only recently bought mine.
