Wire location....

Recently picked up a '73 F100 (390/C6/2wd) & going thru cleaning up & sorting out some of the electrical wiring in engine compartment. The original wiring is pretty intact & in fairly good shape overall but I found one wire (yellow/green tracer) that was cut & is just dangling to the side (see wire with red arrow). Does anyone know where the other

end of that wire attaches to ? I can tell you the wire next to it (green w/red tracer) goes to the "I" terminal on my voltage regulator. At the other side of the connector that yellow w/green tracer wire goes to the horn relay & the green w/red tracer wire goes along back fire wall, then into cab, & finally connecting to harness for instrument cluster (probably for Alt light indicator).
Any help would be greatly appreciated !

Just a shot in the dark here.....

BUT.... look at #14401 in the diagram. It points in 3 places (first), to that plug then on to the harness that goes out to the lights.

AND there is another 14401 pointing to the horn like Redroad said.

Yellow with green trace goes from the horn relay to the horn(s).

Thanks gents. That would explain things. I am missing one of my horns which likely has the connector that marries to that loose wire.

A single horn was standard, two was an option. In '73 the single horn was mounted to the right of the radiator, above the voltage regulator. When you had dual horns the second was mounted to the left of the radiator in about the same location. The wire for the second horn "y"d off of the connector at the first horn and ran across the top of the radiator core support.
Also, the two horns were different, one was high pitch, the other low.
