My switchbacks required no extra circuitry other than wiring the DRLs to the small running lights.
Could you describe or make a sketch of how you wired them into the running lights? Do they operate the same way when set to "auto", or do you need to turn on the parking lights for the white DRL to light? I haven't taken the headlight unit out yet, and I don't have a wiring diagram, but it seems like if the parking lights were off and the "auto" setting wanted to turn the old style DRL's on, the LED's wouldn't know that it wasn't the turn signal being called for.
