Doing some would do you some good, but here is your answer. The Lilli runs on 12v so all you need to do is to tap into a 12v wire from the PSU to one of the Molex connectors and do the same for ground. If I remember correctly of the 4 wires that go to the molex connector, the red is 5v the 2 black are ground and the yellow is 12v. The easiest way probably is to get the vampire clamps from the ratshack or any auto parts store (ie. AutoZone, PepBoys). on the lilli side, if i remember correctly, the white striped wire is the 12v and the solid black is ground.
