Not to put you off but this forum is for computer stuff.

It is?

I'm not sure the wiring diagram will help you too, too much. 12VDC systems are relatively simple. How have you determined it is a grounding problem? Did you test continuity? If that is the issue, you should be able to confirm/fix the issue with a new wire. The trim/tilt hydraulic motor is usually run directly off the battery (mine is at least). Are you able to bypass the switch to eliminate that as a variable?

There really is no wiring diagrams but if you give us the make and model of the engine we should be able to assist you in some type of diagram as that not really boat wiring but engine wiring and we do have diagrams for that.
There are 2 electrical systems on a boat. One is the motor harness the other is the boat harness. Trim is part of the motor harness :)
