Because I am quickly approaching the time when I won't be able to remove my center support channel that houses the busses and MGL I/O Extender, I took several hours today to make a CAD drawing of all the inputs on the items I just mentioned. This is the view from beneath that I won't have (without gymnastics) in the future. On the CAD, I also assigned circuits and fuses for all the equipment I can account for today. There are still openings for the future as well. I then installed the fuses, made labels for the sides of the support channel, reinstalled the channel, made all connections and tested once again. We're good.
