Hey guys over the weekend I removed my stock horn and installed a used air horn from my brother inlaw. It plugged right up to the stock wiring without any modifications. It worked for a few seconds then I blew the fuse. I replaced the 10 amp fuse with a 30 amp fuse and now it works fine. However when I blow the horn my headlights and fog lights flicker ever so slightly,Is there something else I should do or is there something wrong? By the way I have a 2011 rubi unlimited.
