Just with the crimp connector: there should have been 3 parts to it. The third is a strain relief. You double back the cable and clip it on. Not explicitly necessary and in this situation probably OK to go without it since there shouldn't be anything tugging on the cable. Just an FYI.

Nice install. I must admit I thought that the first few images with permanent marker and the hole looked a bit rough and ready. End result is nice though. How is it to keep having to look up?
