The signals are grounded. A pulsed 12volt source goes to the turn signal switch which directs the 12 volts to the appropriate signals. The pulsed 12 volts comes from the turn signal flasher relay.
The hazards are pulsed from a different flasher relay.
There are also diodes to prevent feedback loops in the tail light system.
There is also a diode involved with the turn signal beeper.
Inspect or replace the turn signal flasher first (I guess you already did that). If that doesn't fix it, check the diodes. I believe there are at least three diodes hidden somewhere.
Also, you apparently have some crossed wires if the brake switch affects the signals.
The Clymer diagram has a few mistakes in it, so you'll need some general knowledge to identify the errors.
Here's the errors I spotted in just a few seconds:
The front left signal wire is green and should connect to a green wire, not the oil pressure light as the diagram shows.
The left signal ground (black/yellow) should be tied to the other grounds. The diagram only shows it going to the headlight ground.
The diode on the turn signal relay looks like it may be drawn backwards, or in the wrong place.
There are probably others.
