How to wire the beam splitter connector

Wire the beam splitter by matching the low and high beam pins to your vehicle's stock connector, ensuring proper ground and hot connections, and securing unused pins with heat-shrink caps.

Step-by-Step Wiring Instructions

1. Identify the Pins
   • The splitter typically has male input pins for low and high beams.
   • Low beam is usually the outer lamp; high beam is the inner lamp .
2. Reconfigure for 2-Pin Connectors (if needed)
   • For a 2-pin low beam connector, remove the pin from the red wire.
   • Connect the ground (black) and low beam (blue) wires to match your stock connector.
   • For a 2-pin high beam connector, remove the pin from the blue wire.
   • Connect the high beam (red) wire to the (+) hot pin on the stock connector. You may leave the ground if preferred, but ensure correct polarity to avoid short circuits .
3. Remove Unused Pins
   • Press the tab inside the socket with a small flat screwdriver and pull the wire backward to remove the pin.
   • Wrap removed pins with electrical tape to prevent accidental contact .
4. Secure the Wires
   • After confirming correct operation, cut off unused pins and cover the wire ends with heat-shrink caps.
   • Use a heat gun to shrink the caps onto the insulation for a permanent, safe connection .
5. Test the System
   • Turn on your headlights and verify that both low and high beams operate correctly.
   • Ensure there is no flickering or blown fuses, which could indicate a miswiring .

Additional Tips

• Use a multimeter to verify polarity and continuity before finalizing connections.
• Match connector types: Ensure the splitter input matches your stock bulb type (e.g., H7, 9006) for a plug-and-play setup .
• Avoid glare: Properly aim all headlights after installation to prevent blinding oncoming traffic . Following these steps ensures a clean, safe, and functional wiring of your beam splitter connector for automotive lighting applications.
