Currents should be <5 A since your bulbs are maybe 50 W max (brake & turn filaments). The horn and starter wires trigger relays (~50 mA). You should always describe your car when asking such questions. I expect a 1970's w/ key in steering column. I recall that is a 1-row ~10 position connector from what I've seen in junkyards. My 1960's Mopars use a 2-row connector with "twin-lock" pins. Your bullet terminals look more common. Search for websites that sell automotive terminals. I don't have at hand. Try searching "56 terminal" (common type).
