There are many options to label wires. I never do. I find it much more effective to document what pin does what on each connector (the connectors are also identified). This makes future maintenance or modification easy.

I found using heat shrink printed labels to be best. Identifies the wires at each end/termination in a way that won't fall off with time. Costs a bit more, but well worth it in my view.

+1 for this method. Every wire in my plane has a heatshrinked label on both ends. A year or two years later, I will know what wire is.

Do you use a label maker?

Tefzel comes in any gage, many colors. I don?t need to label a red wire going from the Fuel Pump fuse to the Fuel Pump positive, or black wire to the Fuel Pump negative, etc.... to troubleshoot this circuit.
Ignition wiring, labels help a lot with initial wiring and down the road maintenance, but like Carl, I relay on my wiring diagrams, wire color, and size, most of the time. It is pretty obvious.
High Density harnesses present an entirely different problem. Many are furnished as assemblies. A good block diagram with supplements from install manuals will guide you down the road.

I followed a tip I saw on hints for homebuilders: I printed labels in 6 pt font on my laser printer and bought clear heatshrink from Stein Air for about $.30/ft. In addition to the labels, I used colored wires: red for power, black for ground and white for data (per the advice of my Sport Air Workshop instructor) and labeled every wire at both ends. Adding a label to each wire takes less than a minute. That time investment has already paid for itself during construction, and I'm sure it will be worth more when the plane is in operation.

I'm planning that as well but never occurred to use colored paper. Great idea. Thanks.
