Dave sounds like a few minor things.

Front signals are probably ground. Horns may be to. I chased a horn problem around for two nights. I finally figured it out. I overlooked my NOS date coded relay (that you can't even see). It turned out my problem was inside the actual relay. I took it apart and actually bent the arm closer to the contact so it would work properly. I dont know if thats your problem but if it is, maybe I can save you a headache!
