I'm making quick-disconnects for everything to be mounted in the panel, so if I have to remove the panel I can just undo the connectors and take the panel back to the work bench.
So I'm using Molex-type connectors, which have male and female pins that grab the wires and are insterted in the plastic blocks. I can get up to 6 wires in each connector. Righ now I have 6 connectors scheduled. This one only has 3 wires. Some will have 5 or 6.
