Led Light Bar Push Button wiring

I put this button in my truck a long time ago but never wired it to turn the backlight on when I the dash lights turn on. Does anybody know where a wire is I can wire it into to turn on?

 

I just replaced my switches for off road lights under the the HVAC controls and used the green wire off the heated seat plug. If that clutch switch is back lit tie in the solid green wire. Green is + green/ white is -

 

I pulled from a green wire as well. Under the hood from the headlights so it comes on whenever I turn them on

 

buy an "add a fuse" from your local Autozone and jump into the IGN fuse that is directly in that switch panel you pictured. Viola, let there be light! if you need further clarification, please let me know sir

 

I used add a fuses, switch lighting from "TAIL 10A" and power from "PWR OUTLET 15A" (12V hot, no key needed for tailgate lock and bed lights).
