Before you purchase your HID kit, first thing you need to do is to find out what is the appropriate bulb size ( i.e. H1, H3, H4, H7, H9, H10, H11, H13, 9004, 9005, 9006, 9007, 5202, D1S, D2S, D4S ) for the application.  ONEXHID.com already sort out the correct bulb size for your car headlights and fog lights applications, but if you cannot find your car model in our web site, you can check your headlights or fog lights application at Slyvania auto lighting replacement guide, which is the most comprehensive web site about auto lighting applications.

This installation guide demonstrates how to install a HID conversion kit to your headlights, and you can apply the same installation steps and connection of wires if you are installing fog lights as well.  Note that different cars have different shapes and protections for their headlights; therefore, some extra steps might be needed in order for easier installation, for instance, taking out the bumper so that you can have more space to reach the back of your headlights or fog lights, or you might need to remove some covers that protect the back openings of the headlight light bulbs.  This article can work as a general installation guide about how to connect the HID kit appropriately.

Here is a wiring diagram showing how to connect your HID kit:
