The Wiring Diagram of the 2015 Silverado Headlights
The wiring diagram of the 2015 Silverado headlights is a complex one, with many different components and connections. However, we will try to simplify it as much as possible for better understanding. The wiring diagram consists of:
1. Power supply: The power supply is the battery of the vehicle. The positive terminal of the battery is connected to the fuse box, which distributes power to the different electrical systems of the vehicle.
2. Fuse: The headlight fuse is a 20-amp fuse located in the engine compartment fuse box. It protects the headlight circuit from overload.
3. Relay: The headlight relay is located in the engine compartment relay box. It controls the power supply to the headlights. When the driver turns on the headlights, the switch sends a signal to the relay, which then activates the power supply to the headlights.
4. Headlight switch: The headlight switch is located on the dashboard of the vehicle. It allows the driver to turn the headlights on and off. When the driver turns on the headlights, it sends a signal to the relay, which activates the power supply to the headlights.
5. Headlight bulbs: There are two headlight bulbs in the 2015 Silverado, one for the low beam and one for the high beam. They are connected to the relay and receive power from it.
6. Wiring: The wiring connects all the different components of the headlight system together. It includes ground wires, power wires, and control wires.
