A wire harness is meant to take the power needed for the ballast, via a relay, directly from the battery. Therefore the power does not run through the standard wiring of the car.
This benefits the starting time and in some cases prevents breakdowns.

This is a H4 wire harness that, because of its bi-xenon function, controls high beam as well. This wire harness is suitable for a car with 2 head lights. Is your car controlled by CAN bus? In that case, this wire harness is unsuitable, you need to use a stand alone canbus system!
