Panel turns on!

I started connecting the coax cables, with the transponder and bottom COM cables first (since they don't require messing with the overhead console):

COM and transponder coax cables running through the subpanel

The GPS antennas had too-short screws that were not going through the nut inserts, so I replaced those with longer ones (turned out MS24693C56 and MS51958-68 were the right lengths):

It was then the time we've all (or at least I have) been waiting for - I assembled the panel in place, and started turning on the LRUs one by one (by controlling each output of the VP-X from a laptop):

All of the magic smoke stayed inside!
I played a bit with the system and most connections seem to be fine, but of course there's a CAN bus failure which is preventing most LRUs from communicating - my next step will be tracing that down, then finishing up the wiring (still have to do all of the overhead console wiring, baggage light, securing all the wires, and then later the engine sensors).
