Relays issues open vs closed

Hey guys, I am sorry to post so many time to the board.

I have found the problem why my vacuum pump was always running at soon as I turned my key.

It just so happened that I used a SIPEA 5230 for my vacuum pump ( closed terminal ) just like the rest of the car.
Bad idea! The pump was constantly running!

I have been chasing wires for two days thinking I had a short in my wires. Comes to find out by opening old relay's that came off the car, I noticed one with open terminal!

I think it had a lid SIPEA 5170 ( open terminal ) but I am not 100% sure as the box is badly corroded.

I am running the car now with a BOSH open terminal and everything is running as is should.

Can anyone tell me if the FIAT DINO SPIDER 2.4 or 2.0 used any other opened relays?

I think I have the car pretty buttoned up but I don't want to overlook anything.
