I don't have fitting instructions and sorry to hear about the seller being unhelpful.

Really, its as easy as changing a bulb.

1. cut a suitable circular hole in the headlamp cover just a bit smaller than the rubber gromit.

2. Remove the bulb and retaining clip from the head light and disconnect the electrical connector from the bulb

3. Fit bulb retaining clip over the HID bulb. Position HID bulb into the headlamp and secure the bulb retaining clip.

4. Reconnect the spade connectors to the electrical; plug that was plugged into the old bulb.

5. Feed the remainder of the 2 cables through the hole you cut into the headlamp cover.

6. Connect the above 2 wires into the ballast.

7. Secure the ballast with cable ties (I tie mine to the washer fluid bottle).

8. Switch on ignition and test. If they don't work, swap the spade connectors around.
