Switch panel in overhead sunglass holder

I just got my truck back from Toyota after a 2 week repair of timing cover seal and transfer case seal. Luckily warranty covered repair costs. Before dropping off truck at Toyota I was able to connect the locker switch and wiring. I heard a hum sound from under the hood when I engaged locker switch. I didn't know what to make of the sound so I disconected the wire. I now have time to go over the wiring again and to investigate the humming sound. Hopefully will have it resolved this week.

 

How did this turn out?

 

the wire is still disconnected! I've been working on other projects. I hope to give this another try over the weekend!
