Where does this belong?

[ashx2]

I got this wire w/2 bulbs on it from a truck that I took some parts off of. I am assuming it's for illuminating the heater/ac controls or the floorboard area....but it's a dangerous thing to "assume" things, ya know?

Also, exactly where would this plug into the fuse box? An accessory spot or is there an actual spot for it?

If anyone has any input, it'd be appreciated.
