Hey there, we are going to install the GTS style taillight to G82 in USA. And we need to know which wire in the trunk is the third brake light.

First, we know the black wire is the 3rd brake light wire in the back of the box of 3rd brake light. (The first pic)

Second, we need to know which wire in the trunk is the black wire above. However, we did not find any black wire in the trunk. It seems that the black wire disappears. But in theory, it should connect to the battery. (The second and the third pics)

Could anyone help us identify which wire in the trunk is the correct one for 3rd brake light?

Thanks!
