The trim motor runs on 12v and is reversible. The blue wire is supposed to supply 12v to one side of the motor when the trim button is in the up position. The green wire is supposed to supply 12 v to the opposite side of the motor when the trim button is in the down position. The other side of the motor in each instance has to be grounded through the respective relay to allow current to flow through the motor and run.

The 3 wire brings in it's own ground which is/should be connected to the engine block where the batt (-) is connected. The 2 wire has to get it's ground through the case or internal wire where either has to also be connected to where ever the batt (-) is connected, either mechanically or through a dedicated ground wire.

On the 3 wire as I'm sure is also on the 2 wire is a red wire(s) from batt (+) which actually powers the motor. The blue or green wire just energize the respective solenoid/relay to provide power in the correct direction for movement in the intended direction.
