Are you trying to get those things you mentioned to work without having the ignition on?
If so, you need to go from the battery to a battery switch, and from the switch direct to the feeds for trim/tilt (fused or breakered appropriately, of course.) This will allow you to trim/tilt without having to turn on the ignition key.
All else (except for the bilge pump) should be on accessory switches or the ignition switch (most likely remaining where they are now.)
