If it has to be specific, I need it for a 93 Cobra. I'mm sure any fox 5.0 wiring diagram will do. If not, does anyone at least know where the horn relay is? I'd still just like to have the diagram for future referencing.
About the 15th link down from the top on S&2B's site (veryuseful.com) is for the horn. The link is subtitled Mustang Lights and Horn and has the Horn info at the bottom of the schematic.
