Blue wires on HVAC controler.

On the back of my HVAC unit, there are two wires, one is blue, the other is blue with a white stripe. Which wire goes on top, and which one goes on bottom?

No, they have nothing to do with the backlighting, as that is on a seperate circuit and is done by a single bulb.
