1- First i bought a sunroof interior light from a scrapper, Didnt want to start cutting mine to bits while i tested this one.
2- Next i've drawn using marker through the hole nearest the black sunroof switch (second obolong hole from the right)
3- Then i used the appropriate sized drill bit (8mm) for the 42 Designs wedge LED i was using. Drilled one hole, These LED's are very bright and i felt two would be over powering when driving. I wanted to stay subtle like the standard W8.
4- Trim the drill hole using a craft knife to take away rough edges
5- You also need to trim the hole on the interior light base to enable the LED to fit through
6- Next glue the LED in place, I used a glue gun and also covered the underside of the facia with duck tape to keep the led in place and ensure it was level with the facia.
7- This shows the facia panel replaced onto the base when the glue dried, You can see the LED fits through the base now.
8- Front view now its put back together (Later revised this so the LED sits flush otherwise i found it distracting)
9- I soldered a small length of cable to each led leg, then used heat shrink to neaten the job up and provide some insulation
10- Now go out to the car and pull out the headlight switch (Mines the Euro version for those not in the Uk). Find wires number (16)- Grey + yellow and also wire (12)- Brown. Splice into these using those little blue clips shown.
11- Next feed the wires you've just attatched behind the fuse panel (easy to pull off) , up the A-pillar and across the headlining towards the interior light
12- Remove your interior light (Remember theres two screws keeping it in place , dont just pull at it) and feed the wires through the hole.
Attatch the male clips to these wires when you have trimmed them to the required length. I left enough so the interior light could be removed easily without trying to fiddle with the connectors up high.
13- Refit your light and tuck any spare wire out of the way into the roof lining. Should also point out that i insulated the connectors with tape just to be safe.
14- Finally enjoy the wonders of the Macdaddy light mod without the cost of Vw parts. This light also dims using the dimming switch on the dash
All in all a good days work that cost me less than £20. Thats including the light from the scrappers yard too , so use yours if your brave and it'll be even cheaper.
