I have a C950 on my Cuda. It works fine but I did have to have an ECU replaced early on under warranty. I am constantly playing with the setting to make the drivablity better. Don't get me wrong compared to a carb it runs great, but each time I drive a late model car with standard shift and a V8 I start working to make the Cuda better. As with any EFI wire the power and ground dirrectly to the battery and connect the body, engine and ECU all together with ground wires. PM me if you have any specific questions.
