Not sure about the 2500's but on my '01 1500 the horns are on the passengers side. I know on my '14 3500 the horns are on the drivers side. Sometimes wire harnesses are set up for multiple trims and models. Only way that you could confirm is to put multi-meter on connection and press horn and look for voltage. If it gives you voltage, look for clean area were something was attached. Pretty sure that if a horn was there, it would have been found on the ground from impact. It would have to have ripped wire connector off and sheared or pulled the mounts! Little more detective work needed to be for sure. Sorry to hear about the OPPS that happened!![]()
