Horn wont work, kinda unique problem SOLVED

OK, after a good nights sleep and long day at work I went at this again an 67Dart I owe you. While the schematics didn't match they did show me how the headlight buzzer should be hooked up so I pulled the whole bulkhead connector off an sure enough I found a cut and bypassed wire...It ran to the buzzer while the horns were attached to said cut wire. It looked connected and when I ran power thru it at the bulkhead the horns would honk but I couldn't see it was cut till I pulled it all out. That's also why I couldn't get a reading from the wire in the relay even tho the relay was working. The guy who put this together must have mixed up the horn an buzzer wire and said screw it an bypassed it as it had no horns anyway. By the way the horns I bought were for a 2009 Charger, MOPAR original, guy just wanted air horns. Couldn't believe that they used the same one wire as my Demon did. Sound great and even used original brackets to mount them.
