Ron, this too is plug and play, nothing else required, but with a lot less plug. It is a GPS sender, it is not a speedo cable adapter that screws into the Audi tranny and has the pulse reader on it, that is old technology, and that is why this will work on any transaxle. A foot of wire behind the speedo and you are done, check the VDO catalog. Here it is on the top left, for scale it is about the size of a disposable cigarette lighter.
