Can 7-Way Wiring be Used to Power Headache Rack Lighting Functions

Question:

i am going to purchase the said wiring harness. I also want to tie in my headache rack lights to this harness rather than the factory truck wiring. The rack does have 3 lights on each side tail, turn and reverse light. What is the best wiring with the correct voltage to use to tie into with. Also do you happen to have the color indicator on the wiring harness that i am going to purchase so i can connect the correct turn light, tail light etc from the rack to it. Please and thank you

The problem with using 7-way wiring for a headache rack is that there isn't a dedicated stoplight circuit so if the rack has a third brake light you won't find the correct circuit at this harness. The turn signals, running lights, and reverse lights are present though with the # HM42137. I attached a diagram that shows where you'll find them.
