64 Chevy C-10 Horn Relay not working

[elane352]

Greetings,

Although I have looked at some horn relay postings, I apologize if I missed one that covered/addressed my particular problem. So forgive me if this has already been covered.

Background
=======

I replaced all of my wiring harnesses with an American Auto Wire kite.

The kit has a three blade horn relay.

Since the kit requires a 1-wire alternator (internal voltage regulator), I opted to use the kit's horn relay and discontinue using the OEM relay I had, which was not a 3 blade relay.

If you regard the blade placement as a triangle, the blade at the top takes a red 12-volt wire that goes to the fuse box.

The lower right blade takes a green wire that goes to the horn.

The lower left blade takes a black wire that goes to the black wire on the horn connector cluster.

I have triple checked the wiring and it is reflected as above. However, I have done something wrong since the horn does not work; and it did work before I swapped out the old wiring.

As an additional test, I also hooked up another relay I purchased from Auto Zone this morning. I still had the same no horn sounding problem. This has to be something I have done wrong in terms of wiring.

Any thoughts? Let me know what I am missing please.

Eddie
