Szdystar LED Light Bar Wiring Harness Kit DC12V 2-Lead 14AWG with Remote On/Off Switch and 40A Relay, 3.5m Cable

Szdystar's LED light bar remote control wiring harness kit is a complete 2-lead DC12V wiring loom with remote on/off switch, 40A relay, blade fuse and 3.5m cable, built to power two auxiliary lights up to 300W total.

This ready-made wiring harness is designed for off-road and work light setups where a safe, neat, and remotely switched power feed is needed. It bundles heavy 14AWG supply conductors, a 40A blade-style fuse, a universal plug, and a compact keyboard-style switch with a remote control receiver. The kit supports two lamps (each up to about 150W) on a DC12V system and includes an extra safety fuse for quick replacement.

What components arrive in the kit and why do they matter?

The Szdystar kit ships as a single assembled wiring loom that minimizes cutting and splicing. Key parts—14AWG main leads, 16AWG subordinate control wire, a 40A relay, safety blade fuse and a keyboard switch—are chosen for reliability and easier installation. The remote receiver inside the harness lets you toggle lights up to approximately 30 meters away.

• 14AWG main cable for robust current delivery and lower voltage drop
• 40A blade relay and fuse for overload protection and safe switching
• Keyboard-style on/off switch with adhesive backing for flexible mounting
• Remote control operation with ~30m range for convenient activation

How does this harness protect my vehicle's original wiring?

The harness is intended to connect directly to the battery so the factory wiring stays untouched. Using a dedicated fused feed and a relay prevents the accessory current from running through fragile stock circuits. That arrangement reduces heat build-up in OEM connectors and lowers the risk of blown internal fuses.

• Direct battery feed reduces strain on factory wiring
• Inline blade fuse protects against short circuits and overcurrent
• Relay handles switching current offboard, preserving switch longevity
• PVC and copper construction resists corrosion and abrasion

Which light types and wattages are compatible with this harness?

This harness is optimized for DC12V lighting systems including LED driving bars, halogen work lights, HID setups (with correct relay), fog lights and pod lights. The kit supports a combined maximum of about 300W; for two-lamp installs keep each lamp under roughly 150W to stay within the relay's safe operating range at 12V.

• Suitable for DC12V LED, halogen, HID and work lights
• Maximum recommended total load: 300W (approx. 150W per lamp)
• For 24V systems swap to a 24V-rated relay for proper operation
• Relay rated 40A—replace for higher-voltage applications

How easy is installation and what should I watch for?

Installation is straightforward for anyone familiar with vehicle electrical systems, but the manufacturer advises professional installation or professional guidance. The keyboard switch is small and mountable almost anywhere using the included adhesive, while the universal plug and 3.5m length help route the harness from battery to dash and lights without major modifications.

• 3.5m (≈11.48 ft) cable length for flexible routing to front lights
• Keyboard switch with backing for quick interior mounting
• Use correct wiring hardness and matching voltage for safety
• Observe local laws regarding auxiliary lighting before fitting

Who this is for: The Szdystar remote control wiring harness kit suits off-road enthusiasts, tradespeople and anyone adding auxiliary driving or work lights who wants a tidy, fused, and remotely switched installation. Choose this if you prefer a pre-assembled loom with heavy-gauge conductors, a reliable relay and simple on/off remote control; consult a qualified installer if you are not comfortable with vehicle electrical work.
