First you need to remove the old headlights. You do it like so. Take out the two screws circled red, they are the only thing that holds the lights in place. Now when you have removed the screws, you need to push the light in the blue arrow direction (opposite direction on the other headlight) so you can pull out a ball head screw out of its holder. If it doesn’t go out easy, take a look where the yellow arrow points (in the corner of the wing) and you will see the ball head screw. Spray it with a bit of WD40 or some silicone spray so it can come out easily. Now push/hit the head light out of it.

After you have done that, disconnect all connectors that are attached to the headlight. Now take the headlight off.

After you have done that you will need two connectors or do something similar / same as what I have written to connect the position lights of the marea lights. This is the connector you need. Or you can use female speaker clamps like these. The next step is to get a wire, it must have two conducts that are in different colors or speaker wires with the red line on one of the cables. So you can distinguish the wires. Required length: ca. 40/50 cm, or use more if you want.
