Hello I will help you with your question,
Have you tried your hazard flashers? If they work and the turn signals do not swap the flasher cans in the fuse block. There are two power feeds to the turn switch. the pink and the red/white wire both feed the hazard and turn switches from their own fuses.
Let me know what you have in the way of power on what wires and if the hazards work and I will help you find the fault
Here is the wiring diagram for this switch, let me know what you find
Here is the diagram from a 1991 truck and it sound like it is closer to what you have in your truck.
If you have power at the red/black wire at the turn switch with the key on jump to the dark green/yellow stripe wire. Your rear turn signal should flash fast. If that works jump from the red/black to the tan wire. I want you to go through all four turn signals and see if you can do the work of the switch. Each jump should have the flasher running fast and will verify that all the bulbs, wiring , power and ground are correct. You may have the wrong switch as it sounds like your wiring is a '91 not a '92.
Let me know what you find, it is dinner with Mom day so I will be offline for several hours but I will be back later tonight to hear what you found
Let me know....
If it is a dodge I would bet it is the ignition switch. You can check for power on the yellow wire at the ignition switch as you turn the switch to the start position. I don't know what they wired the starter button to but it might have been the yellow wire and they cut it below the switch. Check right at the switch and if you do not have power there the ignition switch will need replacement.
Here is the wiring diagram for the start system so you can follow along from the fuse to the switch to the relay
Check the connector at the rear of the battery it is often corroded and it carries the start signal from the relay to the starter solenoid. The red wire you asked about goes to the alternator
Let me know if I can be of further help
