Don't have a schematic. Haven't had a 67 Camaro in years. The light blue wire is the left side front turn signal wire and the left turn signal dash light. It does not go to the rear lights.
The light blue wire goes from the turn signal connector, up the column, and ends at the turn signal switch.
The light blue wire also goes from the turn signal connector, through the dash harness, and ends at the inside bulkhead connector.
At the inside bulkhead connector there is another light blue wire that connects to this. This wire goes from the bulkhead connector to the left turn signal light in the dash.
The inside bulkhead connector is plugged into the forward lamp harness under the hood. From the outside bulkhead connector the light blue wire goes to left turn signal lamp.
Check your turn signal fuse. Did someone slip a larger 30 amp fuse in there?
Look carefully at the burnt wire. See if you can see where the burn started from. If the wires on the front left signal lamp or the left dash lamp are not burnt, the problem didn't start there. You will need to replace the wire in the dash harness. When you open up the harness see if the burn get greater as you get closer to the inside bulkhead connector. I can't tell anything from here but usually the bulkhead connector wiring doesn't short out. However, that may have been what happened. After the problem is found, the dash harness fixed, I'd replace the turn signal switch.
Just some thoughts.
