1951 F3 Wiring harness

[Stl-Joe]

Hello,

I'm new to this site. I have a '51 F3 that I've owned about 5 years. Runs great but I've recently learned the original wiring is thread-bare and a fire risk. Would like to re-wire entire truck but having difficult finding a complete wiring harness. Does anyone know if one is even available? Or, do I need to buy separate kits (cow, headlights, taillights, horn, etc.)?
Appreciate any insights.
Joe
