The BU light green wire is connected on both ends and the dark green one goes back through the firewall into the harness. The purple wires are both tight in the connector and plugged into the switch on the column also. The only other wire that I remember unhooking was the wire on the Power brake master cyclinder under the hood, but I have plugged that back in. All the fuses seem to be good, I checked them with the probe and they have power on each end. I'm really stumped............
There's only three wires going onto the TS signal switch. The brown emergency flasher, and the white brake light wires have full time power and the purple turn signal has poser with the key on. The rest are outgoing wires to the various lights. Not including the black horn ground wire for the relay and the horn button.

The orange wire from the fuse panel to the headlight switch carries power for the tail lights and dash lights.

The backup lights run from the fuse panel to the NSS switch and if you have power on the stop tail fuse and the backup light fuse then the problem must be down stream of the fuse panel.
The dome light is powered by the orange wire from the dome light fuse. If it works then the orange wire is getting power at the fuse panel but the ground side of the dome light is the switched side and it is a white wire that grounds by the headlight switch and the door switches.


This is the orange wire at the fuse panel showing the things it feeds.
It also shows the diagram from the key switch to the fuse panel. The brown wire is the accessory wire for the turn signal flasher, and the wiper switch also the heater fan switch or AC if you have it.
It also shows the red wire from the cab junction for full time hot feed to the orange wire and the E flasher. The pink wire from the key switch powers the dash cluster. Notice the junction of the pink wires for the ignition and the fuse panel.

This diagram shows the orange wire going to the headlight switch and the brown wire from the switch which powers the taillights and the front parking lights.
