Need help with tail lights

[Inevitabletyme]

2008 mazdaspeed3** So one of my tail lights broke and I ordered a new set, but for some damn reason you have to rewire the entire thing. Each outside lamp (inside ones are obviously just bulbs) has a black, red, and white wire. From what I saw, from the factory there is a black, green/red, orange/black, and orange/white wire with markings on it. Just wondering if anyone knows how to wire this together, I'm lost. Any help would be awesome.

Seeing as you have a GT, did you check to see if the replacement has LEDs?

Come to find out it was wired correctly, but now the tail lights won't light up at night, and the horn doesn't work. I replaced the fuse, and still nothing. I'm thinking there is a wiring problem...

Brake lights, blinkers, and reverse lights work fine
