Review on Twidec/16MM Raised Speaker Horn Momentary Push Button Switch 5/8&#34 Replacement Parts by Brian Cruz

This product has 6 connections, no instructions and how it should work? All horn relays I know of have a DC ground, why do I need 6 terminals? Is this for running 3 different horn circuits at the same time? It would be nice to have a guide on how to do this. I didn't use it, but kept it for conversations like "Hey Larry, you won't believe this."
