These wires connect to the headlight switch according to the following diagram:
Orange/White Stripe Wire
The Orange/White Stripe wire provides power to the headlight switch. This wire should have a constant 12-volt signal, whether the key is in the on or off position.
If you are not receiving power to the headlight switch, the Orange/White Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Yellow/Green Stripe Wire
The Yellow/Green Stripe wire provides power to the headlight switch when the key is in the on position. This wire should only be active when the engine is running and the key is turned to the “on” position.
If you are not receiving power to the headlight switch, the Yellow/Green Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Yellow/Red Stripe Wire
The Yellow/Red Stripe wire provides power to the dashboard lighting. When the headlight switch is turned on, this wire should provide a steady current to illuminate the dashboard.
If the dashboard lighting is not working, the Yellow/Red Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Black/Pink Stripe Wire
The Black/Pink Stripe wire provides power to the rear running lights and license plate light. When the headlight switch is turned on, this wire should provide a steady current to illuminate the rear of the vehicle.
If the rear running lights or license plate light are not working, the Black/Pink Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Light Blue/White Stripe Wire
The Light Blue/White Stripe wire provides power to the low beam headlights. When the headlight switch is turned to the first position, this wire should provide a steady current to illuminate the low beam headlights.
If the low beam headlights are not working, the Light Blue/White Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Dark Blue/White Stripe Wire
The Dark Blue/White Stripe wire provides power to the high beam headlights. When the headlight switch is turned to the second position, this wire should provide a steady current to illuminate the high beam headlights.
If the high beam headlights are not working, the Dark Blue/White Stripe wire may have a break or a loose connection somewhere in the circuit. You can use a multimeter to test for continuity along the wire and ensure that it is providing a steady current.
Black Wire
The Black wire is the ground wire for the headlight switch. It should be connected to a solid ground point on the vehicle’s chassis.
