OK gang. I just replace the factory horns last night with the Hella electric horns. They don't sound louder at all. Could I have wired them up wrong? There are only two wires each for the factory horns and only two connectors for the new horns. So what gives? I would think one wire would be + and the other - since the horns are mounted to the plastic inside fender. The horns do not have any + or - markings on them any where. So I would think you could connect them ether way. Anyone have a clue?
