Remove the hatch brake light and verify that the unit is getting +12v when the brake pedal is pressed. If so, connect +12v + Ground to the brake light directly, and see if it works. If not, you have a ground issue (usually corrosion) the brake light. Look for the ground connection in the hatch harness.
Repairing the hatch harness is doable, and easier than replacing the whole harness.
