i shouldnt have blown a fuse though, since the power wire wasnt hooked to nething.

Well, there are two power wires. Depends on what you've hooked to what.

For example, on many aftermarket harnesses, the headlight-sense wire is colored orange. If you hooked the headlight-sense wire from your car to the orange wire on the empeg, you might have blown the interior light fuse on your car's fuse panel. Then again, maybe nothing bad happened, it depends on a few factors. In any case, if things don't work after you've hooked it all up correctly, then start checking fuses. Good luck.
