2007 Saturn Sky Alarm/Remote Start Wiring

Hello,

Looking for wiring diagrams for the 2007 Saturn Sky. Having an intermittent "no-start" problem that I suspect to be a damaged/faulty wire, but don't want to misconnect my multi-meter without knowing what's what on the BCM and ECM. Had an aftermarket alarm installed by a company I wish I hadn't gotten such good recommendations for, and not getting the right help from the right people. I'm sure I can figure this out without having to de-install everything so long as I know what I'm looking at.

Diagnostics for these modules are down to the mA and some you can't connect to when they're powered, so I don't want to screw up.

Thanks!
