I'm too brain-fried to process that right now. Tore it all back out. Have battery charger trickle-charging for tomorrow's testing. But I did find three orphan connectors:

1. orange/black - looks like CI 44, Accessory Title Lamp, down near emergency brake.
2. heavy gauge blue/white single connector. I haven't found that in the book yet. Close to bulkhead connector.
3. yellow/yellow/pink. Looks like CI 29, Time Delay Relay.

Okay, so I found connectors that aren't serving a purpose. Unless blue/white heavy gauge has a point, this is just a note. But..
