My wiring was absolutely fine and I had to add a dummy plug to get the brake lights to operate correctly. I had the same exact problem. The dummy plug fixed it. It’s that or putting resistors in. I’m pretty sure it was the brown and yellow wire. I tapped in to the intermediate rear harness. Right before the plug. Make sure you put a good bulb in it and then be sure to cover the bulb.
