'12+ Impreza LED Taillights

There's not much in the way of aftermarket parts for the '12+ Impreza, so when the new 2014 XV Crosstrek Hybrid had LED Taillights, I was more than interested in seeing how they might work on my car.  If you haven't already figured it out, the Crosstrek and Impreza Hatchback are twisted sisters, so they share many of the same parts.  Headlights and taillights are swappable between the two as far as mounting points are concerned, so now that there's a different option available, I wanted to see how it might work, what kind of modification (if any) would be needed, and how it would look on the Impreza.

Subaru's XV Crosstrek Hybrid, the company's first hybrid vehicle, was slated for a "Fall of 2013" release, though they didn't start hitting dealership lots until late December of '13 and early January of '14.  I was able to test-fit one and check a few things out so I could know if it was as easy of a swap as I thought it might be.  To the right, both the Impreza and Crosstrek Hybrid taillights are sitting next to eachother.  The dirty one is the Impreza one (off my car).  You'll notice the points that mount to the body are identical, but the arrangement of the lights is different.

The biggest hurdle is the plug for the lights.  There is a 6-pin connector that plugs in to the assembly that has a different shape on each version.  The plastic housing for the Hybrid LED Taillight is a different shape, although the pins are in the same place, than the Impreza's housing.  They will not plug into eachother in their stock format.

There's a couple of ways to address this mismatch, of which I'll be exploring later.  Once I've found a solution, I'll post a link here to it.  List Price on the taillights are $209.95 each.  Below are the part numbers.

Just another way this Impreza of mine is confusing fellow owners.  Quad exhaust?  Side skirts but no roof rails?  What IS this thing?
