Very easy to install. Remove the plastic splash guard from under the front of the car so that you can access the inside of the air dam. I didn't want to use the switch that came with the lights so I removed the driver's side headlight and connected my lights to a parking lamp wire, (I think it was tan, not sure, perhaps someone could verify), as I wanted the foglights to turn on when I turned my lights on.
I have thought about relocating the lights to the upper vane of the air dam and out to the edges. I chose the PIAA's for their size, and the fact that they are oval, I thought they went with the design of the car.
Silvapain's set up does look good. There was a thread on here recently about Gen 3's and slicer wheels that shows his car and you can see the lights.
