03 A lighting relay harness is most commonly used in aftermarket HID conversion kits to bypass the factory wiring in order to get around complicated electronic control systems or to allow a higher rate of current to be delivered to the bulbs. A Relay Wiring Harness utilizes a 30amp fuse protected power wire that directly connects to your positive terminal on the battery.  An Automotive Relay is used to pull signal from a source (Headlight connector) that triggers power to be drawn from the battery.  There are two sets of cables meant to provide power to an HID ballast.  There are also two separate ground wire terminals that need to be connected to the chassis to complete the electrical circuit.
