If you did it from the above post , then main power, solenoids, trim motor are all working properly. The trouble is from the 3 conductor plug to the control box switch.
Make yourself some leads with the spade connector and insert into the plug housing . I think the vertical slot is power and the horiz slots are up and down. shorting 2 wires will make the trim go up and down. If so, trouble is from the plug to the control box.
