Whats up everybody-

So a little while ago I killed my stock horn, so today i bought a wolo bad boy horn at auto zone to replace it. I hooked it up when i got home...or so i thought. First I got it all hooked up and the horn won't sound, but my truck started fine. So I then un-hooked and re-hooked up the horn, but now my truck wont start. My neighbor thought I blew a fuse(i didnt think so) so he starts pulling fuses and putting them back in. Would this have caused the truck not to start? Other than that I have no clue why the horn or truck wont start (Im more concerned about the truck not starting) So any help or reasons why this is happeneing will be awesome. Oh and my truck is a 2001 ford ranger 3.0L V.6

Thanks guys!
