Have a problem.. my spoiler brake light went out, and they shipped me a new one.. It's single piece CF spoiler with the wire running all the way through. So when taking out the wire, I had to fish the wire through from end to end. I ended up with a string all the way through. Then I just had to attach the new wire to the string and pull it through. Unfortunately, they came a part. Now I'm stuck because I need to somehow fish the wire from one hole to the other.. any tips on how to do this?
