I spent a lot of time, but I didn't get much tangible done. I applied laser printed labels to all of the wires at the main switch panel.
I made a full size template of the panel. We found that we had to move the stack around a little to get everything to fit. The PC Monitor that we wanted will not fit. So we went shopping. I was finally able to find an 800 nits 8.2" display that should do the job. We have one on order from Taiwan.
