Homelink basics....

This is a first draft, 5 minute slapped together Homelink info. I got mine at a junk yard. Pretty basic stuff here...

Please note that your car may vary from my car, so some things will be a little different,

This is the starting point. On the left side of it is a plastic cap you need to pop out, then remove a phillips screw. From that, you can work the sunvisor free, unplug wiring harness. There is a plastic cover on the part the right side latches into, remove it and the 2 phillip screws you will find under said cover. Remove the trim panel that is just past the sunroof controls. Remove the clear plastic plate that covers the light bulbs, look up there and you will see 2 phillip screws, remove and you can then lower the lights and sunroof controls. Your car may have a mini sunvisor above the rear view mirror, it is held in with 1 phillips screw, remove. Take the makeup light out of the headliner.
The non-Homeline visors have 2 wires going to them. Homelink visors have 3 wires. Passats have a different plug fitting for the sunvisors. When I got my sunvisor, I didn't know this and as such didn't think to get some of the wiring harness, I had to purchase plug fitting 1C0 973 119, cost just a couple of bucks. The terminal ends are also different, so I just simple cut the original end off and used some wires from an old harness I've got sitting around. The wires that have the small terminals for an ECM are what I used, be it Passat or Jetta/Golf. You'll need about 24" of said wire.

Pins 1 and 2 are the same on the new system, so I just simply crimped them right up to the original harness. Pin #3 needs power for the Homelink, so....

With all those screws out of the headliner, you can flex it down a little. First get the wire over to where the makeup light is...
... and then to where the lights are. The middle wire is always hot, so tap into that wire. I use a butt connector, I like that better than "scotch lock" connectors. The wire is red with a blue trace (or at least in my car it is).
Put everythign back together and that is it. The Homelink sunvisor is a direct fit.

Why should you send a postcard? Because it is cheap to do and as we all know, the US Post Office is funding it's Super Muntant Army Project with fees from postcards stamps. I would really like to see a Super Muntant Army deliever my mail in the near future.
Thank you.
