Here is the mod that I made.. Legacy shares electrical wiring with Outback..
2000 SUBARU LEGACY. Look underneath the dashboard (driver side) and you will see 2 plastic modules bolted to the steering column. One is usually mounted in Horizontal (Seat Belts Module), the other in vertical (DRL Module). One will have only 1 white connector(horizontal-seat belts), the other (vertical-drl module) will have 2, one black and white. We are concerned about the one with 2 connectors mounted vertical. When you look more closely it will probably have blue label with white letters on it. Here is what my said "UNT DRL ASSY AISIN 84067AE00A," also that module has 2 aluminum plates attached on both sides of the plastic box. Don't unplug the black connector because you will loose most of the functionality of your headlights, just remove the white one. Everything else will work fine, except no more DRL's.
