If you want to add OBC (On Board Computer) to show different information (outside temp, distance etc.) you have to get this feature turned on by a dealer or someone with access to a Durametric scanner then locate a 4 stalk switch assembly. Then you have to order the Volkswagen wires and connector and make up a wiring harness to install. THis will cost you upwards of $85 USD

MY wiring loom is already made up with the proper connectors , no forcing the wires into the white plug on the back of the instrument cluster. Also my harness looks factory OEM and is already made up and ohmed out and ready to install for $45 shipped.
Here is a few pics of the install last week
