Trouble with signals...

Finally have my '76 F100 running,now it's time to sort out my turn signals.Everything appears to be working except the turn signals on the passenger's side.

When I give a signal for that side,I get nothing in the front, and the rear just stays lit and doesn't flash. With my headlights on, I get the same thing except the drivers side front signal stays lit and doesn't flash.

So far, I have replaced the bulbs,checked and cleaned the grounds at the lights themselves,and replaced the flasher.
I'm needing to know where any other grounds that are related to my turn signals may be.Any other advice would be greatly appreciated!

I would suspect the socket that the bulb plugs into. They are subject to break or corrode and lose continuity. Use your volt meter to check the bulb contacts.

sounds like bart 4x4 said, I would suspect bad connections especially on the grounding circuit. Most setups won't flash if one of the bulbs is bad or not working, presume it is not enough load for the single stat to trip.and make the lights blink.

From your description i'd suspect the turn signal switch.

Decided to make an evening of tracing down the wiring front to back and found a few loose ends.....

Under the dash I have a bundle of wires that have been cut, shown in the first pic,and they tie into the plug in the second pic. Can anyone tell me what this is for? Headlight buzzer maybe? Also I found another flasher on the far left side of my dash. Would that be the hazard light flasher?

On the cut wires, it would help to have the colors of each. Can't make it out in the photo.
