How are you guys wiring your roof mounted lights. (I searched)

i think bart did that.. i used a hobby box to hold relays in the engine bay and ran the wires up under the hood molding and up inside the passenger door opening weather stripping

Same here, ran the switch wires through the grommet by the brake booster to the relays under the hood, then up the pass side weatherstripping to the lights.
Not as clean to look at as Barts, but easier to remove if I decide to change things around.
I used a 2" square piece of aluminum box tubing bolted to the floor of the rack from side to side, to raise the lights up enough to "see" over the front cross peice. That way, I didn't have to drill into anything that shows.
