No... I bought the car 4 years ago as a project. It has the original harness in it thats in great shape. Front parking lights are new, plugged into the original harness. Gauge cluster is original with a new printed circuit board. Tail light housings are original, tail light sockets over original. Turn signal switch in column is new. I tested the turn signal switch with a test light, Light blue and Yellow wire from turn has power when the left blinker it turned on, Dark blue and dark green wires have power when right blinker is turned on. I don't have the grill/headlights in yet but I cannot see that that makes a difference since everything else works properly. Hazards work properly.
