No green coming from trim motor

It's very common to see black and white used for 12VDC with boats. There are no sensors in the motor so that's probably the power for it. Not saying the motor is good and going to run if you connect it. As for a particular polarity, it does not matter, the motor is just going to run in the direction the wires are connect and the switch reverses them for which direction it needs to run.
