Looking For Wire

[jrod332]

Last year I installed some firestone airbags on my 05 silverado. I decided it was time for a compressor kit and just installed it this weekend. I got everything wired up except I need to tap into a wire in the dash for the gauge light. Im not sure where to begin. I need a wire that has power when the dash lights come on. Anyone know of a certain wire color.

 

Thanks
