FAQs

What tools do I need?

You will need basic tools like screwdrivers, wire strippers, a crimping tool (or soldering iron), and possibly electrical tape or heat shrink.

Where do I get the 12V power supply?

You can connect to the vehicle's battery or find a suitable 12V power source in the rear fuse box.

What if my car has combined brake and side lights?

In this case, only connect the red wire from the smart relay to the brake light wire. Insulate the brown and black wires.

Is this kit suitable for all trailers?

This kit is designed to work with most standard trailers that use a 7-pin socket.

How do I test the lights?

Connect a trailer or use a 7-pin light tester to verify that all the trailer lights are working correctly after installation.

Can I use scotchlocks with this kit?

Yes, scotchlocks or similar connectors can be used to connect the wires. However, ensure they create a secure and waterproof connection.

What's the purpose of the white wire?

The white wire is the chassis earth, which provides a ground connection for the trailer lights. It must be connected to a suitable ground point on the vehicle's chassis.

Troubleshooting

Trailer lights not working.

Check the 12V power supply to the smart relay. Verify all wire connections, ensuring they are secure and correctly connected to the vehicle's light circuits. Check the fuse.

Vehicle computer detects a fault.

Ensure the smart relay is connected correctly and drawing minimal power from the vehicle's lighting circuit. Check that all connections are correct, with no shorts or loose wires.

Incorrect light function (e.g., brake lights on with indicators).

Double-check the wiring connections between the smart relay and the vehicle's light circuits. Confirm the correct wires are connected to the corresponding vehicle lights.

Pros and Cons

Pros

  • Easy to install compared to traditional wiring methods.
  • Compatible with a wide range of modern vehicles.
  • Reduces the load on the vehicle's electrical system.
  • Includes essential components like the smart relay and pre-wired socket.

Cons

  • Requires a separate 12V power supply from the vehicle.
  • Installation still requires some wiring knowledge.
  • May require additional connectors (scotchlocks, crimps, etc.).

Setup, Compatibility & Care

  1. Preparation: Gather necessary tools (screwdrivers, wire strippers, crimping tool or soldering iron).
  2. Locate the Vehicle Lights: Identify the rear light wires (indicators, brake lights, side lights) on your vehicle.
  3. Connect the Smart Relay: Connect the relay wires to the corresponding vehicle light wires (Yellow - left indicator, Blue - fog lamp, White - chassis earth, Green - right indicator, Brown - right side light, Red - brake light, Black - left side light). If your vehicle uses combined brake/sidelights, connect the red wire only.
  4. Connect the 12V Power: Connect the smart relay to a 12V power source from the vehicle's battery or fuse box.
  5. Connect the Socket: Route the 7-core cable from the smart relay to the 7-pin socket. Secure the socket to the towbar.
  6. Testing: Test the trailer lights to ensure they are functioning correctly.

Compatibility: This kit is designed to work with most modern vehicles. Always check your vehicle's manual for specific wiring information.

Care: Regularly inspect the wiring for damage or corrosion. Ensure all connections are secure and protected from the elements.
