Remove the cover from the sunroof motor compartment.  

This is held in with just simple spring clips. Pry down with your thumb, using screw driver may help here.

Remove the old sunroof switch from the old panel.  

Pry back on each of the retaining clips. Work the switch out slowly.

Install the old knob into the new W8 light panel.

Note the orintation of the black/blue/black tab on the switch, It should face the bulb sockets in the panel.

Before seating the switch, flip the panel over and check that the knob rotates correctly withing the markings on the panel.

Install each end of the VW wiring harness into the existing car harness and the new W8 overhead light module.

Continue to run the wire down the A-pillar to the headlight switch.

You can use a credit card or simillar to tuck the wire between the glass and cover, this actually works very well.

(The A-Pillar cover can be removed to better hide this wire.)

Tipping the drivers side up first, then let the passenger side snap into place.

Push the module towards the front of the car.

Locate pin 17 on the harness connecting to the light switch. Using a Scotch-Lock, tap into the the GREY wire with BLUE stripe coming from the #17 location.

Re-Install the headlight switch, wait till dark, turn on the lights and feel the love.
