Spent a couple of hours pouring over the panel, SteinAir schematics, etc. digging into the details of the wiring.

Here's the latest connections spreadsheet with tons more details (this spreadsheet is also on the Avionics & Electrical Page).  I think this is fairly complete at this point, but will continue to evaluate.  This will allow me to finalize the Molex connectors I'll mount on the sub-panel.
