So I have the wrong socket and relay????

Hmmm.

So 30 is NOT connected to 86 in the Socket? It should not be connected in the relay.

On the relay, 30 to 87a is ok.

So is continuity of 85 to 86.

OK, lets move forward.

You will need to fabricate an external jumper for the relay socket to connect 30 to 86.

Then, try this:

Assuming the relay socket is still wired in and with the relay unplugged.

Right now, you should have 12 volts between socket pin 30 and ground and no where else (if you have 12 volts at pin 86 all the better but I do not think so until you make the external jumper). Please verify and correct as needed.

Use a jumper (a paper clip will do) to connect pins 30 to 87 in the socket. Your horn should sound. If not, verify that you did not accidentally connect the horn to 87a. Correct if needed. This will verify that your horn power circuit is correct.

Now connect your continuity tester to pin 85 and the other lead to ground. You should have no continuity. Press the horn button and you should now have continuity. This verifies that your horn button is grounding correctly. Correct as needed.

Plug in relay and honk happily....
