6) Tape very thin and log flat head screw driver with electrical tape. Now once done insert and begin squeezing the outer most set of clips on the gill light harness which we are replacing working those out first from that outer end of the gill to the front of the car.
TIP: push the screw driver in slightly behind the front edge to grip the light harness and by NOT putting pressure against the outer car body and paint, help grip and pull the harness out by unclipping each set of clips down the line of the harness body from right to left- this on my car was slightly difficult and took 20 mins on the drivers side including breaking the last clip down the line. As you pinch together the harnesses top and bottom clip sets together work the screwdriver to pull hard out ward at the same time.
