You’ll just have to remove the ECM connectors from the ECM and see if it blows the fuse…if it doesn't blow short to ground inside the ECM…if it blows you’ll have to find the short to ground on that circuit…easiest way is using the ohm meter function of your DVOM…set ohm meter on highest resistance scale…one lead of ohm meter on a good ground and the other lead on either end of that circuit either at the fusebox or ECM…you should see OL or whatever your ohm meter shows as an open circuit…anything other than that you have a short to ground…don’t know if there is anything else on that circuit other than the ECM because I don’t have the wiring in front of me !!

What year is your C6?
I have the schematics, and connector end views, but I'm not sure how much help they would be. PM me and i can send you those if you think they will help.
