C7 Exhaust Servo Control
I've got an issue using a factory C7 exhaust on an H3 Hummer LS3 conversion. I cannot find any info on how the 5 wire harness on the exhaust tips are to be connected. If anyone can post wiring on this system it would be greatly appreciated. Here's a link to the project.

The exhaust parts I have are only the mufflers and the tips. They are brand new cut off from a corvette getting a custom exhaust. Right now I can only use them full open or full closed manually. When we power the servos they seem to actually move the wrong way and reversing polarity does not seem to move them at all. The info we have managed to get from someone who is supposed to know is that only pin one, two and four of the five connections are used and they are ground, power, and signal (ground signal). I'm thinking that maybe there are some other uses for the other two pins...
