So fitted aftermarket 55w hids to my factory R32 head lights the standard 35w xeons was utterly useless so got on eBay found a set for £22 delivered from china loads better than what Vw want per bulb (over £100 each) had to do a little bit of modding hardly any tho
Take this yellow wire from the main harness
Strip it this is the live connect the red wire from the hid
The black wire from the hid needs to go to an earth I put it to the brown on the full beam same again just strip it and connect to it , they all go back pretty much like factory like so
Will get some pics later to see how they are
