Brake lights wiring question

Previous owner upgraded tail light and it looks like connectors had to be adjusted.


This is the right side, and everything works fine


Unlike the left side. On the left side the stop lights don't work. So what he did is connected the wire from the right connector across to the left .


You can see the right connector. Brown is obviously ground, and one to the left of ground is the power. It has an extra wire coming out of it.
I need to connect it to the left tail light connector.
It has 12 volts with the brake applied.
The left connector does not provide 12 volts, so the stop light doesn't work independently. I tried checking a few extra wires (probably leftovers from original taillights) for voltage but no luck.
Another confusing thing is that left and right connector wires are totally different color. I wanted to copy wire color from the right side and make the same connections.
I wonder if it's possible to get the stop light working again without running a wire across the from right to left
