I bought this to replace my stock horn. Followed the wiring down to a tee but the horn does not activate. I direct-wire-tested the compressor to the battery and it works. I suspected the relay is faulty, any idea what to do next?

You can bench test the relay to see if it is at fault. 12v supply and DMM set to ohms.
