Reengaged with aircraft electrical wiring today, but was pulled up short by the lack of terminal types and crimps tool. Those are all on order now.
In the meantime, I began the process of measuring and cutting wires for the various connections I'll be making over the next couple of weeks. Once I cut the wires to length, I label them with their individual connection point (on each end of the wire) and cover the labels with heat shrink to protect them.
I also received the electrical terminal nipples I ordered and applied them to the two grounding cables I previously fabricated and installed.
Examples of pre-cut wires with labels on each end.
Grounding cables (to aircraft and to engine) with terminal nipples installed.
