In case you need to connect a 12V electric motor to spin both ways, you 'll need to connect it in a certain way to the 12V battery. The most simple and basic connection is depicted in the following diagram

and it is the most basic connection to run a bidirectional motor from a single bidirectional switch. That's actually how most power windows work in cars today.
In my case, I didn't have the appropriate switch, so I used ordinary AC switches to connect the motor, but the principle is the same. And additionally, what is proven with this video, is that the proper single switch is substituting all these 4 switches I'm using to achieve the same result. And also helps reduse the wires needed to make all these connections.
I'm basicaly immitating the two switches in the diagram, using two single pole normally open switches
So effectively, we need to connect the 2 wires from the motor, to the output of the switches, so that current will flow in one direction at a time. The cord I'm using has two wires inside, one brown and one blue, so I have to connect the two colors in reverse in some cases, so that the power will run in the desired direction.
There is nothing to it really, I'm just immitating the diagram. If you use the diagram as a referance, you'll be safe and have the same result.
If the motor draws too much power, you may need to run it through relays, in which case you will need this diagram:

but the principal remains the same.
The wattage of the motor determines the wire gauge to be used.
And also don't forget to always connect the "Normally Closed" contacts, either of the switches or the relays, to the negative terminal of the battery.
