Brake light issue need help fast

To the best of my knowledge and memory, the white wire begins at brake lamp switch and ends at the signal switch. If there is a white wire behind the left kick panel it isn't on the brake light circuit.
I suppose a vehicle with separate bulbs for brake, park, and turn would have separate ( 4 count ) wires. Doesn't matter so long as you do have brake lights now.
