Headlight signal cable

Hi all
Started installing my ledlight bar today.
Got stuck when wiring it up.
Which one of the cables to the headlights is the signal cable to hook on to for the led bar to light up with the regular headlights highbeam?

Hard to get a good pic with the weather around here. But if you havent figured it out here are a pic that shows the connections
