Don't know how to transfer the spread sheet file, so I copied the text below. Nothing special. Just the wire number and description of the it's function. Missing numbers (i.e., 1-9) haven't been assigned yet. Wires are numbered with the adhesive wiring stickers you can get at Lowes.
Not even sure the spreadsheet is the best way to do it. You could use a numbered text document just as well, or make a little data base if you really wanted to get fancy! The advantage to having the diagram and list in digital form is that you can edit them as you make changes, and print new copies to have on the boat. I'll look at the diagram and go to the list if I need clarification. Should eliminate those, "how (where) the hell did I run that wire??" moments!
The diagram also points out weaknesses. For example I'm thinking I should run the ground in 34 from the Starboard mid ship box directly to the batteries instead of having it run all the way back to the ground at the switch panel, where it goes forward again to the batteries. Probably eliminates about 30 feet out of the circuit. This wasn't really an option until I installed the Starboard midship junction box. In any case, it wasn't apparent to me until I looked at the diagram.

20 - Spreader lights Returns to panel via 23 & 30
21 - Tri color & Anchor masthead light Returns to panel via 23 & 30
23 - Returns 19,20,21 to Port midship box, then to switch panel via 30
25 Wind instrument (Instrument to masthead)
26 Depth instrument
