The red brake light is only on when the e-brake handle is up. There is a switch in the console that opens when it is pulled.
The blue brights light is only on when the brights are on. There is a foot switch under the carpet to the left of the brake pedal that switches between low and high beams.
Typically the dash lights don't work on these older cars, because the dimmer adjustment is shot. Pull out the headlight knog and turn it to the right for brighter dash lights. Sometimes you can find a good spot in the potentiometer, and the dash lights will illuminate. It usually vibrates off while driving and you have to adjust a little bit to keep them on.
A new light switch will usually fix that problem.
Check your bulbs in the front and back to make sure they are working and there are no shorts there. Your turn signal relay might be shot. That is what makes the turn signals "blink".
Definitely get a wiring diagram.
Check and clean the ground wires.
If you make any splices in the wiring, be sure to solder the connections and use shrink wrap. Wire nuts and electrical tape don't last. Butt splices and crimp connectors weaken the wire and the normal vibrations can cause it to break on down the road.
Good luck!

Second thing: Check the rheostat on the headlight switch. These can burn out and kill the instrument lights.
