Default Three wires and their connections at turn signal switch connector.

No diagram needed:
Stop light switch has two wires, one hot all the time (probably orange but might be green) and a white wire that's hot when you mash the brake. The white wire goes to the plastic turn signal switch connector at the steering column.
To test brake lights & wiring up front (under dash):
Brake lights use TWO wires coming out of the plastic turn signal switch connector.
Yellow wire is for left brake and turn light.
Dark green is for right brake and turn light.
TESTING:
Mash brakes and white wire should be hot going in turn signal connector. At the same time yellow and dark green should have power on them coming out of turn signal connector. If that checks good, brake wiring up front is OK.
TRUNK:
Yellow's left and dark green's right. Check for power with brake mashed to make sure nothings broke/lose/disconnected/corroded between front and rear.
NO POWER find the break.
POWER and brake lights should work as long as bulbs, socket connections, and socket grounds are good.
