First time poster here. Hopefully I am putting this in the correct forum, if not hopefully the mods can get it where it needs to be. My son and I just picked up a S&W 8884 light bar at a flea market. The siren was removed by the previous owner. I am really just wanting to get the all of the lights to work if possible. I have taken out the four headlights and checked them - they all work. Does anyone have a wiring diagram for one of these? I have tried looking in other forums and websites, but no luck. I am attaching some rough pictures of the wires I am working with. The brown, blue and white wires were disconnected by someone and I can’t tell where they originally went. The green wire seems to have gone to the siren and is disconnected as well. The black, heavy gauge wire, which I believe is the ground is connected. The red wires that go to the spinning lights are still connected and the yellow wires that go to the headlights are still connected. I did find a YouTube functionality video that showed what seems like a 12gauge Romex wire powering the lightbar, but I don’t know how that is possible without some kind of transformer. I know there are some really smart people on this site and would really appreciate any help/guidance you can provide. Thanks.
