Understanding the Tail Light Wiring Diagram for a 1979 Ford F150
Once you have a good tail light wiring diagram for your 1979 Ford F150, it’s important to understand how the system works. The tail light wiring diagram will show you the different wires and connectors that are involved in the system, as well as any switches or relays that are used to control the lights.
The tail light system on a 1979 Ford F150 is relatively simple, and consists of three main components: the tail lights, the brake lights, and the turn signals. Each of these components is connected to a specific wire or set of wires in the electrical system.
Tail Lights
The tail lights on a 1979 Ford F150 are connected to the parking light circuit, which is powered by the headlight switch. When the headlight switch is turned on, power is sent to the parking light circuit, which in turn powers the tail lights. The tail lights are also connected to the brake light circuit, which is activated when the brake pedal is pressed.
Brake Lights
The brake lights on a 1979 Ford F150 are connected to the brake light switch, which is located on the brake pedal. When the brake pedal is pressed, the brake light switch is activated, which sends power to the brake light circuit. This in turn powers the brake lights, which illuminate to indicate that the vehicle is slowing down or stopping.
Turn Signals
The turn signals on a 1979 Ford F150 are connected to a separate circuit, which is activated when the turn signal switch is engaged. The turn signal switch is connected to the turn signal flasher, which is responsible for flashing the turn signal lights on and off. The turn signal circuit is also connected to the brake light circuit, which allows the turn signal lights to function as brake lights when the brake pedal is pressed.
