Opening the glove box would cause your lights to go out? If that's the case, that's a great clue. The DRL relay is behind the glove box, the DRL is the "Daytime Running Light Relay", it will turn on your headlights automatically. Here's a picture of its connector behind the glove box. I would also check the license plate bulb sockets. They are on the same circuit as the taillights. If they went out already.
But if you move you glove box and have issues with your lights, then your short circuit is behind there, Inspect the wiring behind it for any place where the wiring harness is touching metal, any contact points. Check to see if it has rubbed threw the harness anywhere back there. Vibrations due all kinds of things to wiring harnesses,
Can you take a picture with your glove box out for me? I would like to see what kind of wiring is back there, if it's not too much trouble.
I have added the circuit for the license plate lights, as you can see, they are on the same wire as your taillights and that green wire goes to the taillight fuse.
