This HID wiring harness for the H4-3 High and Low Bi-Xenon kits provide a direct power supply from the car's battery. The wiring harness is a direct plug and play with no cutting or splicing required, simply plug in ready for use.

The harness protects the car's standard harness which was not designed to handle the electrical load of a Bi-xenon setup - the wiring harness will prevent the HID kit from drawing more current than the car's harness can provide. By providing the HID kit with a direct power feed from the battery stable operation of the Bi-Xenon HID kit can be assured; the wiring harness comes pre-installed with a fail safe fuse installed.
