4 Way Wiring

A 4-way wiring diagram for a trailer displays the connections for a basic lighting system, which typically includes tail lights, brake lights, and left and right turn signals. This setup is the most basic form of trailer wiring and is commonly used on small trailers.

In a 4-way connector, the standard color coding typically includes: White for Ground, Brown for Tail/Running Lights, Yellow for Left Turn Signal and Brake Light, and Green for Right Turn Signal and Brake Light.

To install a 4-way connector, align the trailer's wires with the corresponding wires of the connector based on their function and color. Ensure all connections are secure, using appropriate connectors, and properly attach the ground wire (usually white) to the trailer frame.
Check the connections for security and correct color/function matching. Inspect the wires for damage. The ground connection is crucial, so ensure it's well-established. If lights still don't work, a professional inspection may be necessary.
A 4-way connector is appropriate for trailers requiring only basic lighting functions. For trailers with advanced features like electric brakes or additional auxiliary functions, a connector with more pins, such as a 7-way connector, would be more appropriate.
Utilize a circuit tester to check each wire's functionality. Confirm a solid ground connection and look for shorts or open circuits in the wiring. If a specific light isn't working, test both the trailer and the towing vehicle side of the connector.

7 Way Wiring

A 7-way wiring diagram illustrates the configuration and connections of wires in a trailer's 7-way connector, typically used for towing. It includes connections for features like tail lights, brake lights, turn signals, and ground, with an optional wire for reverse lights or additional functions.

Yes, a 6-way wire can be used for a 7-way trailer connection. The 6 wires will cover essential functions such as ground, tail lights, brake lights, left and right turn signals, and an auxiliary function. The 7th wire, often used for reverse lights, is optional and can be added if needed.

To add a 7th wire for reverse lights, connect an additional wire from the reverse light circuit of the towing vehicle to the corresponding pin in the 7-way connector. This requires an understanding of both the towing vehicle's wiring system and the trailer’s connector setup.

Check the connections to ensure the wiring matches the correct pin functions on both the trailer and towing vehicle. Inspect the wires for damage and verify the ground connection is secure. If problems continue, consider a professional inspection.
Legal requirements for reverse lights vary by location. While not always mandatory, they are recommended for safety. Always check local regulations to ensure compliance.
Regular inspections of the wiring and connectors are crucial. Look for signs of wear, corrosion, or damage. Ensure all connections are secure and properly insulated. If in doubt, have the wiring checked by a professional for peace of mind.

Tarp Systems

When your tarp system is not running – the motor will not activate – it is regularly assumed the motor has failed.
  • Ensure that the tarp system components are grounded to battery negative when in use.
  • Do NOT ground to truck frame
  • A normal amperage reading is 10–15 Amps unloaded
  • Ensure the battery is fully charged

Trailer Brakes

Of course you can! All you have to do is purchase the electric brake axles. Once you have your axles, you will cut the wires to the hydraulic pump, and from those wires you will connect the brake power wire and the ground wire to the electric brake axles (generally black, which is the power wire, and white, which is the ground wire).

Trailer brakes are designed to work in synchronization with the brakes on your tow vehicle. Never use just the tow vehicle or trailer brakes alone to stop the combined load.
