This will explain how to flash the front marker lights on an 05 Sport with the turn signals.
1. Remove the two push pins in the wheel wells and look for a three wire plug(black,red,white). You will need the wire in the middle.(red)
2. Next remove the marker light and pull out so you can get at the two wires(black,white).
3. Cut the black wire on the marker light and attach a 6 inch piece of 20gauge wire to it going towards the lamp. Tape the other end up.
4. Next splice the other end to the red wire in the three pin plug.
5. I'm not sure if you need it but I put a diode in between(band facing the red wire) just in case.
Now when you signal the marker light will flash opposite the turn signal.
