1993 mariner 60 hp

I have a 1993 60 hp Mariner outboard motor that I bought used and the trim is not working. I can jump the wires straight to the battery and the trim motors sound like they are working. I checked the hyrodualic fluid and I can not see any. What kind of fliuld do I need to add to the motor? Also the switches are not working, there is a clicking sound when I press the buttons. I have found a red wire that is not connected any where. I need a drawing of some type does anyone have one?
