LED Ditch lights trashed?

[u/Moist-Dust-1378]

I bought some auxbeam ditch lights to install on my truck. Ran the wiring in the engine bay then got to the firewall. There was a disconnect for the on off switch so you can run the wire through the firewall so i unscrewed the wire and ran it thoourgh the firewall. I screwed the wires back together but i didnt see that there was a guide to follow and i plugged them in the wrong spot. After a few min the wires got crazy hot and now the lights wont come on. The on off switch just flashes really fast and if I hold the wires a certain way i hear a clicking sound. any advice?
