A friend has a 1920 Roadster with an extra Black with Yellow Tracer wire under the dash or in the Terminal Block to Switch bundle.

That wire has a round hole terminal on the switch end and a standard Terminal Block type terminal on the other end.

The car has the cast iron running board brackets and no cowl lights, which suggests it was early and had the electric package.

Does anyone know what or why this wire designed or added to the bundle?

The heavy yellow with black tracer wires were used in 3 places. One longer one went from the output of the round shaped cutout device on top of the generator to the leftmost connection of the wiring barrier strip on the firewall. Leftmost is defined here as being on the left side as you face the terminal block on the right side of the firewall. The second yellow/black wire continued from this leftmost connection on the barrier strip and proceeded to the BAT terminal on the back of the ignition switch. The third yellow/black wires was a short wire less than 8" long that continued from the BAT terminal on the ignition switch to one side of the ammeter. For sake of completion, the other side of the ammeter had a heavy solid yellow wire on it that ran to terminal 3 (3rd from left) on the barrier strip. Finally another solid yellow heavy wire continued from terminal 3 of the barrier strip to the battery side connection of the starter foot switch and that wire is the source of all battery power to the car. All 5 wires that I have talked about were 12 GA heavy stranded wire and are the main charging path of the current from the generator to the battery.

Hope this helps.

John, this was not that heavy yellow with a black tracer wire, it was lighter black with a yellow tracer.

How long is it? Will it reach past the gauge panel? Could have been added for a dash light. Maybe it's a horn wire bundled in error. But these are usually plain black.

Ken, my suspicion was that it was for the dash light, as that had a switch built into it. The wire was long enough for that use, after it left the bundle.

The black horn wires are correct.
