A little out of my comfort zone here.. but I have a project where I am making (roughly) 10x kits.. and each needs several 'cable sets' for each.
(ie: main "Arduino compatible circuit/board/(brain)" needs to connect to several other pcb's/assets, like a 3 x digit 7-segment counter pcb.. and 30 x led bar graph pcb....and 1 or two other pcbs).
I have been (painstakingly) making my own wire harnesses out of wire I have laying around.. matching colors, adding male or female connectors on the ends..etc
I'm sure others have been down this road before (me).. and was wondering what you guys do? Do you guys all manually make your own cabling/wire harnesses? Is there a 'go-to' place for custom wire ordering? Can you order Dupont like wires but in specific colors/order? (or similar?)
just curious what others do or have done? or if there is nothing.. and we just make our own custom stuff for use?
26g = wire guage (but you need to know the territory to decipher that). What wrong with
stating the cross sectional area of copper in SI units? I wish people would.

"Wire cross sectional area calculation
The n gauge wire's cross sercional area An in square millimeters (mm2) is equal to pi divided by 4 times the square wire diameter d in millimeters (mm):
An (mm2) = (π/4)×dn2 = 0.012668 mm2 × 92(36-n)/19.5"
I have been buying the pre-made 40-wire ribbon cables with "Dupont" connectors from eBay. You may need to test these just in case - I do this by plugging them into a breadboard so that one wire connects to another and so on, then checking continuity between the ends of the chain.
I separate out pieces of ribbon with the wanted number of wires and with approximately the colours that seen suitable, then I have multi-pin "Dupont" housings bought by the hundred - 2-way, 3, 4, 5, 6-way as well as 2 by 3 for ICSP connections which I fit by carefully lifting the latch on the single pin housings and slipping them off, and insert the wires into the multiple pin housings. I can cross wires over where necessary, sometimes to make the colours make more sense to me.

The formatting didn't quite survive the copy-paste...
An (mm2) = (π/4)×dn2 = 0.012668 mm2 × 92(36-n)/19.5
