I just used a little toggle switch i got from radioshack, cheap and easy.

 

so did you just take the white green/ wire and run it to +(pos) and run the blue /red to the another + (pos) connector? ...

 

My dash lights were out in the n/a fc when I bought it. I changed the bulbs and now it works but even with the dimmer switch all the way up it still isn't all that bright. What should I do now? What it says in this thread? But my tail lights an everything else work fine.
