Oh, this is probably a very common category of mistake! I was thinking of the time I changed my dynamo headlight, and suffered through the frustrating process of fishing the wire through the internal routing in the fork only to realize I hadn't remembered to first thread on the little rubber plug that seals the hole at the top of the fork. So I had to do the wire fishing all over again.
