I would assume that you took the horn contact parts apart in the steering wheel area to replace the turn signal switch wiring. If you don't get the plastic ring and metal contact plate lined up perfectly, the contact plate will be constantly grounding the system, thus allowing the horn to go off. I did that once with my truck, so I know from experience
