This exact, high-quality, reproduction of the original, 1967 wiring system includes multicolored wires with metal pins; a wiring harness; a turn signal-canceling cam, which automatically turns off your signal after you make your turn, a built-in horn switch, and a hazard switch. This wiring system is a direct-fit replacement, which is easy to install on all 1967 Mustangs with a fixed steering column (non-tilt). Simply remove your faulty, stock turn signal switch wiring system and replace it in your factory plug with this brand-new component.
