3) Using a "butt" connector, tap these 2 wires together. Tap them as close as you can towards the main connector (gives you enough slack if you need to every change your halogen bulb)
Here is how I did it,
This will allow the lowbeam xenon light's to turn on.
Mind if i ask what type of headlights you have? Did you have any error codes
