I’m new to the forum, I’m having issues with a new light bar not working at all.

Im hoping someone here has also had issues with aftermarket light bar install. I used the wiring harness that came with the light bar and wired it directly to the battery and I can’t even get the switch to light up, I take it off the battery and I use my Milwaukee battery that I can adjust the voltage between 12-18 volts and it’ll turn right on and everything works as it should . I’m ready to pull hair out lol.

Happen to have any pictures of the harness set up with battery vs Milwaukee connections?
