I made these up with with a cut and paste from the 1969 factory prints.
This is the way I do it for future trouble shooting.
I find having something that looks like the original prints on them is helpful for reference.
I did find some errors on the wires at the turn signal flasher IIRC.
Corrected on here.
I don't believe there is any connection between your reverse lights and your flashers.
IF the lines don't go anywhere on these prints that means the are irrelevant to the flasher/stop/turn.
I have simplified prints for a 4 speed car that I've made.
The factory prints are all online as he said.
From working with that I can tell you that the prints are sort of cobbled together on that system.
I'm guessing you have a bad switch and the power should be on one side of the plug at all times and the switch complete the circuit only in reverse.
Easy check with a meter.
Perhaps pull the plug off and check that.

The internals of the switch is always a mystery on Chrysler prints.
(Same with the wiper motors . They trouble shoot up to the switch. After that the tech was going to just change the motor I imagine.)

This later work drawing contains a representation on the 1969 prints of what the switch does from a later A body set of prints which shows the internals.
The pin numbers are self explanatory follow them from one to the other.
