Relay control

Hi.

I would like to know how to control a relay of the Finder brand, model 40.31.

The coil needs 6v. I read that I need a 2n2222a transistor but I do not know how to connect it, I have not found a good scheme.

See this Motors 1
Last three schematics on the page are good schematics.

Thank you.

Edit:
It works great, thank you!
