In this video, we learn how to install chase tail lights on a Mustang. First, you need to remove the rear trunk panel and trim piece. Next, prepare your tail light kit by following the directions that are given to you with the package. Next, cut the tail light wire. Now, put on your turn signal and take note of which light it still blinking, then mark it with electrical tape. Now, swap that light into the in board position and run the new wires by rewiring the new lights into the tail light. Do this on both sides of the car and test out the lights before you replace all your parts. If everything looks good, replace the parts you took out and you're finished!
