The same way ours do, since you need to look for an integrated stop/tail/turn, just like our cars come standard with (the dual contact bulb has everything in one bulb).
Three wires, just like your car has currently, a ground (black), turn signal (blue on 95 and 98 for sure), and regular lamp (can't remember wire color).
User: Josch used those, you can see pics in his webpage in his sig.
