More 348 horn issues

OK I know where compressor is and yes it is there......

Here's where I am at in the no blow horn:

Fuse is good (25amp)

From what I can tell (testing headlight confirms) Ferrari does not energize fuse block but waits for relay to trip sending power through fuse to horn (same principle for headlight). My guess is that pressing the horn button energizes relay coil (by grounding) and then sending power through fuse to horn.

Please tell me if I am correct and then I can complete the testing of system....any input would be appreciated much.

I cannot believe I am in this again.
