Can anyone help me to identify some of these parts on my 2002 Mercury 150 HP Saltwater motor? I think I know what some are but they don't match up to what I see online when I search for the parts. EDIT- Sorry I thought the pictures would show in the post with my description. Each pick has what I think the part is and a description or question. Thanks Yall.

first two show a temp "gauge" sensor/sender. temp gauge only..production merc doesn't use screw in sensors... three should be water pressure.. forth purples are "switched, key on hots" (12v) for optional/added stuff and or different models... fifth shows a thermal valve for carbs and tha "over temp" sensor.. tha single tube from tha thermal should go up to tha carbs.. other is intake for valve..
