Hehe, I like it just because it allows me to pull into my driveway without flashing the neighbors bedroom with my headlights.

I did mine a couple of years ago, and I can't find the detailed Tutorial on it, but this one shows what the module that you unplug looks like. I assume it's the same on the Outback.

Edit (again): That link was for a new age Impreza, which might work, but here is one for the Legacy. (You have an Outback Legacy right?)
