Where can I get the buttons for the right side of the steering wheel controls?

Can I make them all push lock button with the light like the cruise control button has?

I want to make them for my amplifiers, volt meters, line output converter, etc

Whether you can re-purpose the controls to do what you're thinking is kinda beyond me, but here's the "How To" thread on adding the OEM audio buttons to the wheel.

Yup, sounds pretty involved. They are not separate wires for each button, pressing each one changes the resistance value of the circuit, which is then interpreted by the radio or bcm.
