Hi

Suggest that you might consider Teflon jacketed #24AWG wire. Buy small spools of the wire and then twist the three colors you want together using an electric drill.

The Teflon wire insulation holds up better when soldering then PVC type for sure. If you are going to crimp the pins then likely does not make much of a difference. I find the Teflon wire a little harder to strip but it stands up better.

Just a suggestion

Cheers
