Steps to Wire a Dual Headlamp Relay

Step 1: Disconnect Your Car’s Battery

The first step in wiring your dual headlamp relay is to disconnect your car’s battery. This will prevent any electrical accidents from happening while you work on your car’s wiring.

Step 2: Locate Your Car’s Headlight Wiring

The next step is to locate your car’s headlight wiring. This will usually be located near your car’s headlamp switch or fuse box. You may need to consult your car’s wiring diagram to find the right wires to work on.

Step 3: Connect the Relay to Your Car’s Headlight Wiring

The next step is to connect the relay to your car’s headlight wiring. You will need to connect one wire from each headlamp to the corresponding pins on the relay.

Step 4: Connect the Relay to a Fuse

The next step is to connect the relay to a fuse. You will need to connect the power pin of the relay to the fuse holder, and then connect the other end of the fuse holder to a power source. This will protect your car’s wiring from any electrical surges or short circuits.

Step 5: Reconnect Your Car’s Battery

Once you have completed the wiring process, you can reconnect your car’s battery. Then, turn on your car’s headlight switch to test your dual headlamp relay. If everything is working correctly, you should see both sets of headlights turn on at the same time.
