Only one is connected though, the other is just there as a spring to hold it tight I guess.

There should be that one ground pin, then one other pin will have 5V one it, it should be either pin 1 on the left, or pin 4 next to the ground pin. The other pins are not connected so you can't short them. Just be careful not to short pins 4 and 5 if those are in fact the two "live" pins. There's no telling what will blow...

I would check between pins one and 5 and see if it has 5V first, if not, carefully try pins 4 and 5!
I just got +5.36v on pin 4 !!! On a free Harbor Freight VOM so the thing probably isn't the most accurate in the world but I wasn't about to use my GOOD VOM

Pin 5 is Neg as you stated. I got nothing on Pin 1 so I carefully checked pin 4and 5 and came up with the reading.
