It's designed to avoid splicing into your factory circuits — instead you connect directly to the battery and the single light, keeping installation cleaner and reducing risk to the vehicle's electrical system. The loom is insulated with durable PVC and uses copper conductors for reliable current flow, with an overall length of about 3.5 meters to reach most front-mounted lights.\u003c\/p\u003e\n\n\u003ch3\u003eHow do I install this harness safely?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward if you have basic wiring experience, but professional installation is recommended for unfamiliar users.
