- Connectors that securely link the harness to the headlight assemblies, switches, and other electrical components.
Here's a simplified look at how the power flows:
- When you activate your headlights, a signal is sent through the control wires to the harness.
- The harness then directs power from the car's battery, through fuses and relays, to the appropriate headlight circuits.
- This power energizes the headlight bulbs, illuminating them.
A malfunctioning harness can manifest in a variety of ways, from a single burnt-out bulb to complete headlight failure or intermittent operation.
