Vacuum pump wiring question ?????

It's the same pump.

I ran wire into the dash and tapped into the 'key on' ignition wire where I had spliced in my MSD...(brown I think,maybe blue,I would have to check in the morning)it seems to be working fine.

...now if I could just get my horns to work...

One came with the car,the other I pulled out of an 86 Ramcharger ,so I doubt they are both bad.

The relay is making a sort of springy clicking sound when I press the button.
Does that mean it's working or does that mean it's shot?
I know it's original because I was the first to dig into the insulation to find the mounting bolt.

I traced the wiring and couldn't find anything obviously wrong.

Any help would be much appreciated,I would like to get it inspected this week and it won't pass if it won't blow.

Thanks again!
