Strange Turn Signals/Brake Lights??

so i have a 68 dart that when i got it the left turn signal didn't work but all other lights did. so i converted the p/s dart to manual steering with the correct column and box. i checked the wires from the plugs and they were both the same. so i was driving tonite and noticed that when i hit the brakes both front turn signals come on?? haha like brake lights on the front. all the lights still work and so do the turn signals?
any ideas?

Mine is kinda doing the same thing.

Without the lights on, the rear lights come on when you hit the brakes.

With the lights on, the right light goes out

both rear turn signals work without the lights on, the right one doesnt work with the lights on.

I think it may be something with the front signals though, as i replace the front and rear bulbs and the left front stays on when you hit the left turn signal, the right one doesnt light at all.

The right indicator on the dash is lit all the time when the lights are turned on.

I love electrical problems.
