For the wiring you will need 2x 000979009E, they come in packs of 5.

You will also need T25 screwdriver, trim tools, flathead screwdriver, heat shrink tubing, insulating tape, something sharp to cut wires.
Optional things would be cloth tape to give oem look and stop wires from rattling inside door and would definitely recommend some spare door clips as some tend to break when taking door card off.



Start by prying off trim and speaker cover to reveal 2 screws, final screw is located under handle.



Once screws are removed there is a tab you need to press, as shown in the picture, which undoes a clip inside the door. Then use a trim tool to pry door card off. Some clips can be really reluctant to come off, best thing to do is use trim tool to pry door card off enough to get your fingers under and pull. You will need to roll down the window, then push up to slide the door card off.



Once door card is removed, unplug connector from door module and disconnect wire from door handle. The door card should now come off completely.



There is a small gap that you slide the end of the light bar through, then push each of the clips into their slots, you should not be able to see the light bar at all when clipped in, if you can you haven't pushed it in enough.



Now to the wiring: You will need 2 wires for each door. Mark one wire with tape at each end, so you can identify this as your ground wire. Strip one end of each wire and twist the end.
Plug the other end of each wire into the connector. The ground wire (with the tape on) goes into plug 1 on the connector. Once this is done you can tape up with cloth tape.



You are going to tap into the wires for the door handle led so remove the connector, then remove wires from connector. To remove the wires the top of the connector slides off, then use the flatheaded screwdriver to release wire from connector. Strip part of the cable to reveal wire, use the screwdriver to part the wires in the middle. One wire will be solid brown, this is the wire you will put your ground wire through.



Slide your wire through and twist round. Do the same with live wire. Then slide heat shrink tubing over and heat up to seal cable. Put wires back into connector, brown wire goes to plug 1 on connector. then connect back up to door handle led.



Now plug the other end of your wiring to the led and then attach your led to the light bar. There is a small clip on led that goes into a slot and secures it to the door card.
Connect everything back up, take care to make sure wire for door handle is put back properly.
