In addition to dropping my fuel tank this week to replace the vent lines, and flushing the cooling system and putting in new coolant (VW blue with distilled water, btw) my one other job this week was to install a new set of horns. Hooked everything up per the instructions with the horns, and no horn. Searched the archives and found where you answered the very same question a couple of years ago, and rewired the relay per your instructions-horn worked! Your instructions were no where close to those in the box, but yours worked.    Thanks!   Jeff
