52 Plymouth Not tractor but more info

I have a unit that fits on the steering post. I can tie into the park lights easy because don't use any how.It is how to tie into brake cylinder switch and tail lights..Any advice appreciated.

Google up

"Add on turn signal switch diagram"

All sorts of them show up.

If you know the model, brand or part number of the switch, even better.
Some require separate brake light bulbs.

Are your brake light bulbs single or dual elements?

You might have to do some turn signal lights or change the brake light sockets to accommodate the dual element bulbs.

I will be facing that same thing if I ever get my 52 Plymouth running. Since people don't use arm signals anymore it will be a good idea to have directional lights. I have a 52 business coupe.Stan

Depending on how it's wired, if there is a single brake light wire running back, you will need to run another wire to separate the stop lights.

Both stop light wires will wire into the turn signal switch.

The stop light switch will wire to the turn signal switch, it will cancel which ever stop light when that turn signal is called, making that side flash.

Brake lights and tail lights are together in the one bulb..

Your turn signal will use the same half of that bulb as the brake light does--the brighter of the two. You should be able to trace which wire that is and connect your turn signal switch accordingly.

What method of turn signalling has been used with your car for the past 68 years? Seems to be working OK, why fix something that ain't broke?

I will ad some thinking. The parking lights are the running lights and cannot be used for turn signals. the brake lights work from either a pressure switch on a brake line (possibly at the brake master cylinder). The other option is the use of a mechanical switch attached to the pedal lever, or a pivot to linkage. (could be out under the hood, or under the dash. The brake light switch output wire will be the input to the signal lever. There is also a power lead to the signal lever. When the brakes are applied with the switch in the middle, both lights get normal brake switched power. When turning, and not braking, the light in the turn direction, gets power from a turn signal flasher, blinking. The other light bulb or filament remains in tail light mode on both sides of the car.
If turning and braking, the brake light on the turn side flashes as above, the non-turn side gets brake light power from the brake light switch.
All this means there are 4 wires, a power wire with a flasher in it, a brake light switch powered wire, and two wires to the bulbs in back. If there is only two wires going to the tail lights, an additional wire must be installed to create a separated path to one of the brake lights, and the other brake light wire needs to be cut and spliced into the Turn signal switch.

ARM OUT THE WINDOW

FWB ...... I know there's not much traffic in Saskatchewan but if you still have your left arm, I'd say you've done pretty good. What part of Saskatchewan are you from?

East of Yorkton on the Man/Sask border..

It is 4door and grey.

I had a '52 Plymouth my last year in high school and until I went in the navy (8-59), pretty sure it had factory turn signals.
