I'll check my local ford dealer for the power button but i think i'd be better off buying it online and installing it myself knowing my dealer ...!! ermm another ques guys. i've seen the button light up. Is that connected to the dimmers? The tutorial shows connections to two wires. What are those for, is one of them to light it up and the other for its actual use?

Also, seen some other forums, they make the circuit diagrams look more complicated than just justting and joining wires =S seems like you need to connect some fuse?
