Not sure if the video linked by Andrew does this or not, probably not, and is inline with the parking lights, meaning it's actually getting it's load power from the same line. Not sure how much those will draw, but as a good general rule of thumb it's not a good idea to add after-market stuff to an existing used line, as they do things as cheaply as possible without any user add-ons to a circuit in mind.
In which case for our 05-09's:
Easiest to use would be either side's parking lamp circuit to trigger a relay for it (likely both, unless your going to wire the halo ons from the same circuit, so you need two relays).
Tracing the wiring in that area
Dark green = 12v on for left front (drivers side)
Black with a pink stripe = 12v on for the right front (passenger side)
Hit radio-shack, or any automotive store and get a 12v, 20-40amp SPDT relay if this kit does not come with one. Around $5.
Pin 86 = ground
Pin 85 = the dark green or black with pink stripe wire from the car
Pin 30 = Power on line to the halo lights
Pin 87 = Fused battery power line, or an unused properly rated(amperage) line from the BEC.
I split the above, as both groupings of 2 are interchangable, meaning 85 could be ground, and 86 could be the dark green/black with pink stripe, etc..

If you're going to go the above route, and not cut, then resolder the 3 leads together, I'd crimp but still use heat shrink tubing over, or wrap tightly with good electrical tape, then zip-tie at the end point so it doesn't unravel over time. Just need to make that as air-tight as possible to avoid corrosion, and obviously to avoid shorting shiznat.
Edit: I started to say the side-lamp for use, but this will flash when that side's turn-signal is used by the SJB... so yeah, eeeeee, wrong. Altered the above to parking lights for either side.
