Rear Brake light signal

[SVTGUY21]

Hey team, I installed a soft topper onto my raptor and I need to move the third brake light onto my cage to meet local requirements. I purchased an aftermarket LED third brake light, but I cannot seem to find which pin provide signal out of the tail lights. Any help would be great.

The 3rd brake light output is circuit CLS17, Yellow with a Gray tracer from the BCM. At the 3rd brake light, it’s Pin 8. The circuit is transistor controlled, so the aftermarket light will need to have the same current draw as the factory one to avoid DTCs and failure of the module.
