I'm assuming there is some VW or Audi part out there that was used as with most of all the rest of the new Lamborghini electrical components and I've yet to find the part number of cross reference. I went as far as looking up the Lambo part number in the VW / Audi catalog and it gave me a light bar cross reference to a Audi A6. I found someone on EBay that was parting out an A6 and bought the light bar with the connector (just wanting the connector) and what I got back was the same part number but completely wrong for a roadster. I'm guessing that the cross reference was for a coupe and not a roadster and the connector / light bar is completely different.
