We're planning on rewiring the tail lights on our 49 Chevy 3600 this weekend.

-What gauge wiring should we use for 6 volts?

-Is there a website I can geek out on that carries wiring and connectors for old trucks?

-Long shot here; do folks have pictures of wiring they've done so we can get some ideas on how to run it, connect it, clip it, loom it.. etc?

This site has been instrumental in helping us get the truck running.

THANK YOU!
J&K

Hy JungleJames, the factory gauge for the tail/stop wiring under the truck is 18ga., up to that point it was 16 Ga. hope that helps.

18 ga will work fine for tail lights it can handle 7-10 amps no problem. I always go larger 16ga. Make sure you have a good ground. I ran a separate ground. Not stock but can keep you from having issues over time.

This wiring diagram for a 1950 truck shows the gauge for each wire.

Indeed it does. It shows 16 ga. for the tail/stop lamp. 18 sounds a bit light to me for a 6v system but I'm certainly no expert.
