I was looking through the 996 manual (Diagnostics part 2, 90-D132 page3) which shows the coding instructions for the instrument cluster, and came across the following:

"Cruise Control: This menu item enables the instrument cluster to be coded after replacing the instrument cluster or after retrofitting a cruise-control actuator."

There is another reference to coding after retrofitting the OBC. This being the case, I would have thought that Porsche would have issued a TSB about retrofitting. Do you know if they have done?

I have not seen a TSB on Cruise Control retrofit... but that does not mean it can't be done.

There are two types of clusters the old type and newer (MY02 on) type. That statement is in the newer cluster section (K22; K23; K27; K31; K35). I think it is likely easier to retrofit cruise on the egas/new cluster cars.

I looked at the wiring diagrams and it looks like a piece of cake to wire it up on the 02 and later cars. The cruise controls are in the instrument cluster, unlike the earlier cars that are controlled by the DME. Therefore it would appear that you could just fit the stalk and it would be a simple job to wire it into the cluster. The reason for asking is that a friend of mine is looking to buy a 2002 car, but really wants cruise. If he finds the right car without cruise, he wants to try retrofitting.
