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.

Or, get yourself some colored shrink and do the whole job with about half
the time. Same drill, but this time the first digit is twice as wide as the
rest of them.

One of the more troublesome aspects of aviation electrical work is the
fact our wires are usually NOT color-coded.
