Well, got 90% of it done, but it looks like one of the wire harness' is missing the pins for the OnStar J2 (12 pin ) connector, so -- got a call in to Gen5Diy and hope to have it soon. Sucks as I have to go out of town and hoped to have this out of the way so I could start my LSA Supercharger install
Hope I can get them soon...
