I can almost guarantee the polarity is reversed (positive is negative and negative is positive). The thing most aftermarket companies don't realize is that the car uses a constant power with a switched ground, and therefore the wire coming from the switch is actually not the positive wire (as the wire's not coming FROM the switch, and rather going TO the switch). Reverse them both and flip the switch again. Don't do one at a time, as that will just blow your fuse anyway. If that doesn't work, make sure your fuses are not blown and then try it again. Let us know if that works. (I mean the SIGNAL WIRES and not the wires that connect to the battery)
EDIT: Your original bulb uses a 9007, which is going to have the center wire be the constant power source for the lights. The high beam ground is to one side, and the low beam ground is to the other. You've obviously found the high beam ground as those work, and a light bulb will work with the polarity reversed. You need to flip them anyway understanding that the center pin on the 9007 harness (the blue part in that kit) will be constantly powered, and not grounded. PM me if that doesn't make sense, but it should get you moving in the right direction. Correct me if I'm wrong, but the fogs probably aren't working properly right now either with the wiring wrong.

Reason: Added info for 9007 connector
