Craig, Regarding the cruise control... I'm pretty good with wrenching, fabricating, and some basic electrical, but the cruise control was one of the go to items that needed a lot of expertise. I had a guy who was extremely sharp with auto electrics and computers figure out the logic of the Porsche C/C functions. He took this information and talked to a guy in Arkansas who was building interface modules that would allowed the GM ECU to talk to the Porsche controls. The interface was $500 plus...

It works fairly well, it's a little lumpy at slow speeds, this might have to do with the cam in engine. However Kyle my guru installer said the interface has logic and will in time learn the system and become better. whether that's spin or not, I don't know. At freeway speeds it holds the speed perfectly so I felt it was a success.

In the effort for total factory, Kevin at North Hollywood Speedo disconnected the Porsche solder trace at the circuit board from the C/C icon on the dash and left me with a pigtail that connected to the interface module. So now my dash C/C icon also lights up.
