Yo Ryan,
Welcome!
What year do you have?
I will assume its a 91 with Borg Warner 1356 for now.
1356 Manual Shift Wiring Diagram
If you just acquired the Bronco, its possible that someone or road/trail debris cut the indicator light switch wires (2) and were spliced together backwards. Check the wires near the connector.
Or indicator light wires were reversed. The switch connector could be forced in backwards, but doubt it.
Check those wires as well.
I will post this fir now, because I have lost all this narrative once so far.
