The horn relay is nothing special, just a generic "bosch style" 4 pin relay. Every VW has a couple and many other cars do too. VW refers to this one as Type 53 or 24 and stamps that number on the top in big type. You can buy the generic version at any flaps, often sold as a fog light relay or horn relay, or driving light relay. Commonly used as fuel pump relays as well, as in Vanagons. Typically 30 amp, sometimes 20 or 40 amp, all more than enough for horn use. Sometimes the generics have a 5th pin that isn't used for what I did. The 4 pin relay has pins labelled with numbers and is used thus: 30 load in 87 load out 86 relay control input pin 85 relay control ground pin Mark
