Blower motor relay

[chrismoore701]

I am pulling my hair out trying to figure out my blower relay on my 79. The low speeds do not work on my original. Bought a new. Low speeds work but high blows a fuse. I have bought three different and they all do the same.
The original will click when you ground pin 4. And add power to 3. But no continuity between 1 and 5. New switch continuity between 1 and 5. But as soon as you add power to 3 it sparks. A dead short. 3 relays all the same thing. See pics. What am i missing? Am i wired correct?
