So tonight I finally wired up my battery in its new location:

and the electrical panel has been moved to directly under the seat:

My problem is that not all of the electrical stuff works now. I have a headlight, turn signals, tail/brake light, but that's it. No neutral light, no oil light, no starter, no power to the coils, etc.
I visually inspected my fuses, and I put my multimeter across them and they all checked out. I disconnected and reconnected each electrical plug in the panel to no avail. I'm sure there's something simple I'm missing, but I can't see it.
Everything was in working order before I pulled it out. The only wires I changed were the + and - leads from the battery. I replaced them with 4 gauge wire. My multimeter reads 0.5 ohm between the negative terminal and the valve cover. I suppose I should have measured that beforehand so I could get a good comparison.
What could I have messed up by pulling the wiring to the panel and reconnecting it? I have mostly new connectors there, all of which have been cleaned and packed with dielectric grease.
I un-mounted the panel and let it hang loose:

Thoughts? Suggestions?
