AkosL writes in with a prototyping tip:
Try teflon insulated wires. (Or other heat/wear resistant insulation materials). Why?
The insulation is very resistant compared to “common” insulator materials. Both mechanically, and heat resistant (the one right in front of me is rated to temperatures between -60°C to +200°C). You could solder just few millimeters from it for a short time.
Pretty thin too. Not suitable for high currents, but you can push one wire through one hole in a proto-board.
Available in several colors, i have about six colors.
Of course they are not exactly cheap, but not crazily expensive: iirc bought @0.5$/meter.
