Dear Harrybar:
By the 22nd series they were putting a separate switch on the dash for fog lights so that should be a clue because the fog light function was separate from the headlights. If you want the lights to do something rather than just glow I would go for a fused relay taking it's feed directly from the battery with coil feed from the panel lights and a switch to ground. This way you won't be taxing any of the old switches and wiring. Fused relays for the headlights and park lights would also increase performance as those old switches need some relief.

Haven't seen a schematic specifically for 46-7 accessories but here is one for 41-2 Clippers showing how they did the lights. Since switches are the same, would think it might be applicable.
It would appear the fog lights were independent of headlights but tail lights were on via either switch. I would also add a relay to control them rather than rely on an old switch. Same with headlights -- I would be tempted to take the load out of the switch. IMHO, if you keep it stock with no relays, it's going to be hard to do much without using the original circuit breaker since it is integral with switch -- not like the later ones where it was a stand alone assembly. If you are going to go modern, I would suggest using another circuit breaker such as the stand alone version used later -- not a fuse. Believe headlights were 20 amp. Make sure it's the type I or self resetting style. That way if there is a problem, lights will flash on and off rather than just quit completely as they would with a fuse or type II or III breaker. As an added attraction, the fuses on back of headlight switch, one of which would feed the fog lights per factory drawing could possibly be replaced with circuit breakers -- if there is room side to side and type I style is available. I haven't used one but there are breakers which fit in some regular style fuse holders but do require extra space to the side. Both breakers shown are available at Napa as well as most good auto parts places. The standalone type is first breaker photo and the glass fuse replacement is the second.

Thank you for the help.
I ordered 6 volt relays for the headlights and fog lights from Chevs of the 40s. Each fog light drew 5 amps when I tested them. I bought H6006 Halogen headlight bulbs. Each low beam drew 6 amps and each high beam drew 7 amps when I tested the lights wired directly to the battery. I will replace the headlight sockets, too. I thought they would draw more current, but they were bright I will mount the relays on the firewall near the voltage regulator. Attach file: ![]() ![]()
