    Is the engine running when you are trying to use the trim switch?

    Does the bilge pump work? Should turn on and run constantly while engine is running.

    Can you be clearer about what wires got changed?

    Yes the engine is running when i try to use the trim switch.

    the bilge pump works , i changed the trim motor wires with the bilge pump switch just to see if the trim motor works.

    You will need to make sure all the connections in the ebox on the circuit board are good and not corroded. If that is in order, you will need to use a meter to check operation of the trim switch. The switch essentially receives 12v + power from the same orange wire as the bilge pump, and then alternates it on the green/w and blue/w to the trim motor depending on which way you press the switch. The trim motor should also operate if you press and hold the bilge pump button when the motor is not running. This provides battery power to the orange wire.

    Sounds like a bad trim switch. Check continuity (resistance) through the switch in both up and down positions. If that is good hold down the bilge pump button and make sure the orange wire has +12v.
