I've received a couple of PM's regarding application. I guess I didn't directly state it, but this control will ONLY function with the stock NPP system found on certain 2008+ C6's and all ZO6/ZR1. It was an option that was added from the factory (factory RPO code NPP)
If you are unsure if you have an NPP system, check the fusebox under the passenger foot area and look for a 10A fuse in the most bottom-right position. If you don't have a fuse there, you don't have NPP. Also, you can always look in the center tailpipes with the car off. There will be baffles that are closed and the outside will not have any baffles.
