The solenoid on mine only had like 3 or 4 wires going to and from it. To make sure not to damange anything, pull the solenoid off and put use a meter to detect which wires raise and lower the unit. If you get the wrong wire it will just raise/lower it the opposite of what you're trying to do.
If you still can't get it to work try www.iboats.com
and search the forums. They were pretty helpful when I had an outboard.
