I still don't understand the wiring. The wires are stripped on each light fixture. The wire are stripped on both ends of a segment of extension cord, and the wires are stripped on an extension cord that plugs into a wall. I don't understand where I'm fusing the light fixture strippings first off. Then I'm not sure about the extension cord because I don't know where to start with the extension cord to the light fixture. Am I fusing the plug holding portion to the light fixtures, or am I fusing the plug holding portion to the end of the segment that has two ends stripped? I guess I fuse one of the light fixtures to the long plug in portion, then I fuse one of the light fixtures to the extension segment. After that I fuse the extension segment to the already fused (long plugin to light fixture).
