W8 Interior LightTools Required:
1. No.2 Point Pozi-Drive Screwdriver
2. Small Flat-Head Screwdriver
3. Your choice of electrical connection (scotchlok, soldering iron etc)
Before starting disconnect the battery neutral wire!
Step One: Using the small flat-head screwdriver, gently prise the lens from the existing light (from the windscreen side)
Step Two: Remove the two pozi-drive screws
Step Three: Pull gently down on the windscreen side of the light, then pull towards the windscreen to remove it from the cavity.
Step Four: Fold down the small visor (between the light cavity & the windscreen) & remove the single pozi-drive screw. The visor will now pull off. Put this somewhere safe.
Step Five: Attach the "adapter" loom to the W8 light & the existing loom. Feed the long wire through the cavity & out of the headlining by the windscreen. If (like me) your W8 light didn't come with the extra loom, you can get them from vw_teeside on ebay for about £8
Step Six: Hook the rear edge of the W8 light into the cavity & then push upwards on the front edge to pivot the light into position. It should "click" when it's fully home. I had to remove a small amount of foam from the back left of the cavity to allow room for the new loom.
You now should have something like this:
Step Seven: Remove the fuse box cover & console end piece by carefully prying out with small flat-head screwdriver.
Step Eight: Route the wire along the top of the windscreen, down the A-pillar (tucking it into the headling as you go) & into the space behind the fuse box.
Step Nine: Using your preferred method of electrical connection, connect the wire to the blue/grey wire from the dimmer switch.
Step Ten: Refit the side trim, fuse box cover & visor
Step Eleven: Reconnect battery & look at the pretty light!
