Drivers SIGNAL not working
By driver signal I assume you are refering to the instrument panel turn indicators.
Does this car also have fender mounted indicators?
On our end, one frustration is being told something is "good". It means nothing. The filaments look good. That's informative. We tested the bulbs off the car and they work. That teslls us something. We did a continuity test on the bulbs and there is x resistance on each. That tells us something.
Now lets go through this systematically.
Weird thing is that when I took all the fuses out, we still had headlights.
The headlight switch is a really a multi-switch.
The headlight circuit gets power from the main splice to the B1 terminal on the headlight switch. There's a 15 amp breaker inside the switch.
The parking and tail lights get power from the alsways hot side of the fuse box. That wire goes to B2 on the headlight switch. They remain seperate from the headlight circuit. Inside the switch, there is a branch from B2 to the dimmer for the instrument panel lighting.
Flashers are fine.
Does the driver's signal work with the flashers on?
Hazards are powered from the always hot side of the fuse box. They a share a fuse with other items.
Signals and parks work at the tail lights.
These are seperate circuits.
Their bulbs share a ground.
No brake lights now either
Brake lights share some of the same circuit as the turn signals.
But there is no power to the turn signal flasher with the key off.
We have power at the passenger ground wire. Drivers is the the one that's not working.
Also the top left wire on the firewall plug should be ground and it's got power.
There are NO ground wires to the multi-connector on the firewall.
In fact there are hardly any ground wires on these cars at all.
I'm emphasizing this because it very easy to damage something not knowing this.
Do you have a Dodge or Plymouth shop manual for '69 ?
It shows exactly what each connection is for, along with the wire color and size.
The Tach is also flickering when the car is running and the tach needle clicks with the passenger signal.
The needle clicks? Moves?
That seems like a good clue too.
Where is the tach power coming from?
Is this aftermarket or factory?
OK. we'll break this down in a bit since its only is useful in conjunction with the rest.

I'm going to be the hard *** here. It really seems the frustrating is from not understanding the system. That's making it much harder to narrow down.
I agree its likely something is crossed.
