Shop truck wiring kits at Truckstop Group

Proper wiring is essential when installing auxiliary lighting on trucks and commercial vehicles. Incorrect connections can lead to voltage drop, overheating, blown fuses or electrical faults, particularly when high-output LED lighting is involved. Wiring kits simplify installation by providing correctly rated components and structured layouts.

Truck wiring kits typically include relays, fuses, switches and pre-terminated cables designed to handle the power demands of auxiliary lights safely. Using a dedicated loom helps isolate lighting circuits from the vehicle’s main electrical system, reducing the risk of interference or damage. On modern vehicles, wiring kits may also be used alongside integration modules to ensure compatibility with CANbus systems.

Selecting the right wiring kit depends on the lighting type, power requirements and vehicle configuration. Quality kits are designed to withstand vibration, moisture and temperature fluctuations common in commercial environments.

Truckstop Group stocks wiring solutions trusted by workshops and fleet operators, supporting professional installations that prioritise safety, reliability and long-term performance.

Frequently Asked Questions

Do LED lights need relays?

In most cases, yes. Relays help manage current draw and protect switches and vehicle wiring from overload.

Can one wiring kit power multiple lights?

Some kits are designed to support multiple lights, but power requirements should always be checked to ensure safe operation.

Are wiring kits vehicle-specific?

Many are universal, while others are designed for specific applications or lighting types. Integration kits may also be required on newer vehicles.

Can I install lighting without a wiring kit?

It’s possible, but not recommended. Wiring kits reduce risk, simplify installation and improve long-term reliability.

Do wiring kits affect vehicle warranties?

Correctly installed wiring kits that do not alter factory wiring are less likely to cause issues, but it’s always best to follow manufacturer guidance.

How can I tell if the wiring kit will work with my truck?

Simple. If you add the item to your cart, and let us know your vehicle registration using the option on the cart page, we'll check the part fits before we process your order. If it doesn't match the vehicle, we'll get in touch to discuss your options.
