02 GL1800 w/Auto Pilot
I can't tell if you're serious or just pushing the tape idea here...
I'm an old retired electronics technician.
when I would get into a box full of wires, and need to service it, and no wiring diagrams handy or available....
I pulled out that little red plastic container of 3M numbered tapes out of my tool box...
I am Dead Serious, it is an easy way to be able to put things back together.
It is cheap, it is effective, and it works.
