you can get one of these, and hook it up to the Battery post in the engine bay.
my DRLs came with a similar harness.
It autodetects when the car turns on and off.
Only downside is it will not turn them on with unlock *with the Angel eyes).
i used to have mine just shoves in the headlight and tapped off the angle eye bulb wiring, but the connection wasnt good.
