I have a 2015 GMC 2500 Sierra and am trying to figure out how to connect a strobe to the switch in the overhead console.
Question, do you have to take out the 2 small screws and pull the entire unit down to snake the wires through to the third brake light? Once I connect to the green and black wires is there anything else I have to do to power the strobe?
Thanks

I seem to recall reading something that warned that those clips break very easily, so be gentle
