There is a vacuum line attached to the back of the headlight switch on the dash. When you pull the switch out to turn on the lights this allows vacuum to open the light doors through rubber vacuum lines. When you turn the lights off this cuts the vacuum to the lights and a spring opperates the doors and closes them.
The headlights require a vacuum to operate down. If there is no vacuum they remain in the up position. You may have a vacuum leak such as a disconnected or broken vacuum line. I have also seen the vacuum reservoir can rotted out and unable to hold a vacuum.
Yes, the headlights should be completely identical.

The fuse box in the 1977 corvette is on the outside wall under the dash on the drivers side - about as far up in the corner as they could put it.
The headlights turn off because you have accidently hooked the stereo's power wire onto the headlight relay wire. When you turn on the stereo, there's not enough power left to run the headlight relay. Thus, no headlights. Re-wire the stereo.
I can' help with a diagram. I can just suggest you do them one at a time, so as to not need a schematic.
You have a vaccume leak
