I'd just make my own to be honest with you. You can easily make something to cover that space above your CD player (assuming you got a single DIN sized aftermarket one) and just put the switches in that. Also, switches are very easy to install. It's basic wiring, how come you are planning on 4 switches? One for each light seems like what you are planning. You basically just wire up the LEDs according to the instructions and wire up the switch along with it for each one.
I'll see if I can find a wiring diagram for you, back soon......
