Depending on whether your car has the Electro clutch I believe the upper or horn section has either 4 or possibly 6 or 8 wires in total. I can't tell for sure how many you have but looks like 4 with maybe a modern wire taped on??
Without EC, it has 4 wires and from the start point it goes about 18-20 inches toward the horn where 2 horn wires exit and other two continue on another approx 16 inches to the carb starter switch. Horn will have the spade type connectors as does the starter switch.
