What would be a website or anything of the sort that you could find a horn wiring schematic for your 1987 firebird formula 350?
I am currently a member on Thirdgen.org, it is a great technical website they also have an awesome classifieds section with over 40,000 members all who own 1982-1992 Firebirds or Camaros. just be sure to become a member and DO A SEARCH, they hate it on there when people just ask and dont search. There is a section on there that is all electronics. VERY GOOD SITE. Have fun, 1985ws6transam is my name on there.
