... which (please correct me if I'm wrong) refers one to MIL-C-27500, which specifies two completely different color codes, both of which apply to multi-conductor cables. For single wires, white is specified. The nice thing about standards is that there are so many from which to choose!You can certainly choose your own preference as this is the Experimental Category. For most everything, I still refer to the original accepted aviation standard practice source. FAA AC43.13-1b

The AC does talk plenty about the details of good wire marking....but could you explain more what your take on wire color from AC43.13-1b is? (I'm thinking you mean use white and label, along the lines of what I'm planning...but not sure.)
Most people just use the white Tefzel wire and label it.
Are you building or debugging?
I tried the tiny computer-printed labels inside clear heat shrink and gave that up after about 15 minutes. W-a-y too much time and trouble.
I've decided to run coloured wire out to the extremities of the aircraft to assist with wire tracing in the future. This is aided by the fact that Stein has a massive range of colours in 22AWG. It's ok for the big lads to run all white wire given that they print circuit designations along the entire length of the cable, but I don't have any fancy printer, so I'm just labeling at the end. I am running into one problem however, and that is getting varied colours in the shielded cable, either a varied outer colour or internal colours. The reason this is important for me is that the Garmin CAN bus will use a white-white/blue wire, but I also have other items that will require twisted shielded pair running to the same device (eg. autopilot servo to trim servo power wire). Does anyone know anyone that stocks anything other than the white-white/blue twisted shielded pair, as Stein and Spruce only have the one configuration listed? Alternatively, if I can't find anything I'm thinking about running a sharpie down the outside off the wire to assist with ID in the future using one of these:

Although $50 is a lot to spend on a piece of plastic. It makes me wish I had a 3D printer.
As another point, does anyone know what the thin plastic strip/ribbon is that is included inside the twisted shielded pair?
Thanks.
Tom.
Nice find on the heatshrink printer. There aren't many out there that can print for wires as small as our 22AWG.

Cheers,
