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.

Note: These are general and generic instructions and are not for any specific HID kit. We highly recommend professional installation. This DIY should only be used as a guide.
Here is a wiring diagram showing how to connect your HID kit:
Disconnect the car battery. Remove the factory light bulbs. If your vehicle’s headlights have dust caps, please remove them as well.
If your vehicle is equipped with headlight dust caps, drill an 1′′ (24mm) hole to accommodate the wiring harness.
Remove the xenon HID bulb from the protective casing. Be careful NOT to touch the bulb. Handle it by its plastic base. If any grease or dirt gets on the bulb wipe clean with rubbing alcohol.
Put the bulb’s wiring harness through the dust cap (as illustrated). Insert the xenon HID bulb into your headlight and secure. Connect the spade terminals (positive & negative) to the factory headlight wiring harness.
Insert the rubber boot (on the wiring harness) through the hole on the dust cap (which you drilled earlier).
Connect the bulb to the ballast. The quick dis-connects will “click” once fully secured.
Find a mounting location for the ballast. Use the ballast bracket, screws or zip-ties as needed.
- Do not drill holes on the ballast box.
- Mount away from moving components.
- Mount to a secure location.
- Avoid hot areas that might lead to ballast overheat.
Check your vehicle’s headlight fuse. Make sure it is rated at 20AMPS or higher. Replace the fuse with a 20 AMP fuse if your headlight fuse is of a lower rating.
Reconnect the battery cables.
Turn light switch on and allow your new xenon light to run for 10 minutes.
