did you check power at the relay? The switch on the column should just supply ground.

Honestly haven't had time between work and what not. I was gonna continuity test it to eliminate it as the column. I just wanted all the info so when I do find time I can get it all done

Just for shifts and giggles, try grounding the steering shaft in the engine compartment with a piece of wire to a good ground or the battery ground. Then try the horn.

Checked my relay and between two terminals I have a little resistance between the other possible combinations I got ol. On the actual connector under the dash I read 12 between two connectors and 1.08-2v between another combo. Also tried jumping the wires between different combinations horn didn't sound. I also do have rust on the ground terminal to the horn itself. I will try again tomorrow on lunch to get more measurements.

If you jumpered power to pin 87 and the horn didnt sound then you have an open on the wire to the horn itself. Read the resistance from pin 87 to the horn wire and see what you get. Also is the new horn a 2 wire or 1 wire setup? The 1 wire requires a ground by mounting through the assemble to common the grounds. If it is a 2 wire setup then you need to ground the ground wire to the chasis.
