(Beginner) I'm trying to have the input voltage on the relay transfer over to the NO once the relay is made. Is it possible to just make a parallel circuit using the input voltage? The relay actuates at 12vdc and I need 12vdc to power the motor on the NO terminals. Any help would be greatly appreciated.
I'm not sure what you mean. All I have left is the 12v at the input to do anything with and I still need to power the motor. Right now the motor is on the NO with no power source.

Yes. If you have a changeover relay, with the common contact connected to +12V, and loads connected from the NC and NO contacts to 0V, you can make the relay latch by powering the coil from the NO contact.
To close the relay, you need a pushbutton from +12V to the top of the coil, i.e. in parallel with the NO contacts. To open the relay, you need a normally closed pushbutton between the bottom end of the coil and 0V.
You should connect a reverse-biased diode such as a 1N4001 across the coil, otherwise when current to the coil is interrupted, the back-EMF from the coil will cause arcing in the pushbutton, and electromagnetic interference.

Either I, or everyone else on this thread is misunderstaning the question.
As I understand it, He has a 12V source which is powering the coil of a relay (no Idea what the relay is connected to). He has no other source of 12V. He want to run a motor from that 12V source whenever the relay is energized.
So why talk about latchiong the relay? There is not power source to run the motor when the 12V that is activivating the coil is off. So why not just connect to the motor to that 12V source?

This is a typical case of poor information.
In #4 it is suggested that power is transferred from one motor to something else.
Depending on where the signal comes from, if manually, perhaps a change over switch would do.
There must be a reason for proposing a relay, latching is one so that the power does not come back on after power is cut and restored. High power is another, car starters have a relay (solenoid) to handle the high current. We need more information.
