Hurm.
OK. This is how it works: B+ power from the battery passes through a
flasher module (those little cans that click), through a switch, on to
each signal light filament and then to ground and back to B-.
The catch is that you can't just tie all the wires to each signal light
together at one single throw single pole, because power will then flow to
all the lights, even though the 4-way flasher is off and you want just the
left turn, right turn or brake lights to work. Normally, the signal light
switch handles this by switching these functions seperately.
Were it my problem, I'd find a 4 pole relay (there may be solid-state ways
of doing this, but that is beyond my ken). Use a switch and flasher to
control the relay (you may have to use a flasher designed for LEDs if the
relay won't pull enough power for a thermal flasher), let the relay handle
getting power to each signal light without tieing them all together. The
relay will act like 4 individual switches, sending power to each light
seperately. When the relay is open it disappears, electrically speaking,
and normal signal and brake function is restored. You might have to
cultivate a friend in a boneyard to find what sort of cars have the relay
you need.

You can tap into the signal light wires where they come out of the
steering column. There will at least be one cold wire for each signal
light, one hot from the signal light flasher, one from the brake light
switch (hot only when brakes are on), one hot for the horn. The colors
_might_ be:
Pink From Emergency flasher
Red/White From Signal flasher
Black/White Horn relay
Lt. Green RR turn/brake
Lt. Green/Black LR turn/brake
Green RF turn
Pink From Brake Switch
Green/Black LF turn
Poking around, it looks like 4-way flashers are an issue for early
fullsize jeeps. Here's one thread:

You might try there and see if they have a more elegant solution than
mine. I recall that my `62 Econoline has 4-way flashers as a dealer
installed option.
The thread above include a link to a solution for early 60s Ramblers:

And a last thought: You _could_ gang 2 double pole, single throw toggles
(each pole is really a seperate switch) together and wire them up like the
relay diagram above, with the switches between the battery and the flasher
module, and between the flasher and the lights. It would be ugly, but it
would work. Make sure the switches can handle the load -- don't buy those
cute little sub-mini switches.
Warning and disclaimer: Automotive batteries are high amperage devices
that will happily destroy wiring, start fires and generally cause grave
damage to vehicles, property and persons. Given a shorting conductor of
sufficient size, batteries can explode. Understand what you are doing,
the hazards and dangers before beginning. Any work the reader undertakes
is entirely at his or her own risk.
