Yes-at least on my 53 Manhattan there are 5 wires (high beam headlight, low beam headlight, parking lights, Left turn signal, right turn signal) bundled together coming through a hole on the left side of the firewall that go forward to the junction block in front, where they diverge enough to reach their respective slots. The bundling in this case is just electrical tape wrapped around the 5, but I believe that this is the original design.
