1st clue, 1968.

The black wire inside goes to the parking brake warning switch and the black wire under the hood is connected to the brake pressure warning switch on the splitter from the brake master cylinder.

If you ground either wire, the red warning light on the left corner of the dash will illuminate with the key on if you still have the light and if it has a good bulb.
