1) Remove the two wing nuts located on the top of the factory roof rack that secures the front of the wet clothes basket carrier.
2) Place the light bar with the open angle facing forward, so the bar sits flush with the roof rack. Use Lock Tite on the security screws and tighten washers and screws using security bit.
3) The same security bit can be used to unbolt other parts of your roofrack if you wish to run wires under the tubing.
4) Install lights and switch according to instructions.
