Original harnesses had round, black, 2 piece crimp-on connectors (commonly known as bullet connectors) for the tail light wires. The tail light came with a pigtail long enough to reach through the frame to where the harness wires terminated. Some of the vendors sell a deluxe tail light which has this pigtail with bullet terminals on the wires.
