Special Relay Harness: "Long Ballast Life relay harness" is designed to provide your ballast with a constant steady power stream without any spikes. This Relay harness features power pack modules right before the ballast to store up power but does not effect the operation of the harness or light in anyway. It is a great relay harness to have if you want extra protection for your ballasts.
Your HID bulbs will have connectors to connect your factory connector to the ballasts. All you have to do is connect this in between that connector for the input of the harness.
Your relay harness will work with your existing HID KIT power Harness.
This is why there is no need for bulb selection.
