And it takes about 20% more time to do the wiring on a NEW airplane or a
COMPLETE REBUILD on an old one to get the good old aviation white wire
insulation and down to Staples for 9 marking pens; black, brown, red,
orange, yellow, green, blue, violet, and gray. (0, 1, 2, 3, 4, 5, 6, 7,
8, and 9) Assign each wire in the aircraft a number in accordance with a
little thought about what the numbers really mean. With three digits you
can have about 800 wires, with four digits 8000. Above that, you are
making a 747.

Each wire starts off with a double stripe of the lead digit. Then one
stripe on the insulation for the second digit, and so on. FOr example,
wire #234 would start off with two thin red stripes around the
circumference of one end of the wire, then a single orange stripe, then a
yellow stripe. THen a CLEAR shrink sleeve around the whole "number".
Repeat at the far end.

And skip wire #233, or any with repeating last digits. Otherwise you end up
with red-red-orange-orange. You couldn't distinguish that from wire #322.
