Discovery 3 lights - Alterations to new lights.

Now its onto the wiring of the new lights. The 9 pin connector socket at the back of the new headlight unit is not suitable so must be removed. I decided to keep it in place as a seal against moisture ingress into the light unit.

Remove the socket by turning (you must overcome the small plastic stoppers) and the socket drops into the light unit. Use twine or similar to pull the wiring at the back of the socket and cut all the wires close to the socket back.

Now drill a hole in the side of the light unit and feed all the wires through this hole, place a rubber grommet around the hole and seal the wires in place with a suitable mastic. Finally turn the light unit upside down so that the socket drops down near the mounting hole, pull it through the hole and turn to lock it back in place.

Each of the 9 wires that are sticking through the hole must be fitted with male type spade connectors - the white and green wires are for the headlamp levelling system (wiring of this not covered by this guide) so if these are not required, tape the ends up.

Now the headlamp bottom strip should be attached to the new headlight, the photo below shows how it clips into the base of the light unit, remember to install the metal connector clip onto the end of the strip so it can be secured against the wing.
