I just bought 2 new Altezza LEd smoked tail lights. On the back of the brake/turn signal lights there is an orange wire and a black wire. where do these connect to and what are they for? Also what kind of bulbs does a 2000 civic ex take for the brake lights? i purchased 7443 and they dont seem to fit. Please help me out here.

 

1) Altezza style tail lamps, unless you are actually trying to fit Lexus tail lamps to the car.
2) Without a brand, or anything else to go off of, how is anyone supposed to answer what wires are for what? Either trace them manually, or power them up and see what lights up with each.
3) If they're actually LED lamps, why are you trying to stuff a bulb in there? Sylvania lists the 2000 Civic as using 7443 bulbs for the brake lamp, but an aftermarket housing will use whatever it was designed for, which may or may not be the same bulb size...
