Im having trouble with no turn signals. Have check all fuses with test light all are good. I have hazards,brake and running lights. Ive checked and have no power to the orange/yellow wire to the flasher which is new. The manual sayes the org/yellow goes to fuse box but dont see it, were does it gets its power from? I ran jumper and signals work. Its a 1974 f100 THANKS for any help or advise
According to the factory wiring diagram the orange/yellow wire goes from the flasher and ties into the wiring at the windshield wiper switch.

To save you from looking for it, the turn signal switch is on page 5 location 61B.
There are two flashers behind the dash, one for the turn signals, a H/D unit for the emergency flashers. Both look identical, but the H/D unit has a louder CLICK.
1973/74 F100/350: There are two T/S switches, one for M/T, one for A/T.
