how to wire a DC gear motor with an AC adapter?

I'm pretty new to working with motors and wires, etc. Just got a gear motor from monster guts for my FCG project. That one seems pretty straightforward.

But how do you wire one of the 4 rpm 12v DC gear motors, like this one...

What kind of adapter is appropriate for this motor? I want to use it for a simple tombstone head peeper. Thanks.

I finally found just what I was looking for here if anyone else is interested:

I had to do the same thing with a few wiper motors. It was the only way I could use a 12 volt 5 amp power block to run my motor.

I built two of these with the same motor. I have two dc power supplies that I used my volt meter to test. One runs at about 11 volts which gets me a good slow motion I really like and the other is around 13-14 which is a little faster than I would like but still okay. If you have a way to test the volts on the ac-dc power supplies do, I had one that said its out put was 12v and it was over 20 so it can vary quite a bit.
