Hi.

Let me start by saying that I had my bar and lights installed by a company that specializes in doing this type of thing.

The lights are connected to the high beams, but in order to put separate switches in (I have two, one for each set of lights) I used the relays and wire harnesses that are made for the lightforce lights. Each relay has it's own fuse and is connected to the battery and the high beam wire. When the HB are switched on, the relay pics up the signal from that wire so that the lights go on...if the switches are on. I can have just HB on if I want...I like that.

The person you might want to contact is well armed. He installed hella 4000 compact HID's on the rally light bar. Here is the link to all his pics and posts.
