Tail light wiring diagram

[dyeguy1212]

Anyone hand a link handy that would help me determine which color wire is the brake light on the LY tailight harness?

2022 bighorn with LED tails

Looking to tap into it for my 3rd brake light on my hard cap.

CHMSL wire tap for topper check this thread. On the 4th page it shows where to locate the wire without the adapter.
