We found this chandelier at IKEA in the as-is section (apparently formerly a floor model), and as it seemed to be in perfect condition, 50% off the retail price seemed like a good deal. Unfortunately, we didn't realize it was missing a vital part: the ceiling mount AND a wiring adapter (as seen in step #3 in these instructions). So basically what I have is an unmarked two-stranded wire (the connector was removed from the light fixture's cord as well), and no way to connect them to the ceiling box.
I purchased a stand-alone canopy kit, which can replace the missing canopy mount, but I cannot seem to figure out where to find a power adapter to connect to my ceiling wires and the light fixture's wires. I've figured out that I definitely need something through trial and error -- connecting the wires directly to the ceiling lines results in blown bulbs (with the wires tried both ways). I may just need to know what that little cube thingy is actually called, so I can look it up.
It also occurs to me that this could very well NOT be the problem... The quick connect boxes I'm seeing don't actually have any electrical bits in them, they're just faster than using wire nuts. Maybe the wires in my ceiling are screwy.
