Help me identify these mystery wires. Mercruiser 350

Hi, Just buttoning up my Mercruiser 350 install. I didn't remove the motor myself as the previous owner had a shop do it so I don't know where everything goes. Just wondering if any of you know where these wires and hose go. Pictures are attached. Thanks.

1st pic --- to engine ground stud on bell housing. 2nd pic ---- purple wire is 12v+ key on power, maybe coil? Black with ring terminal might be an extra wire, it's a ground wire. Black with bullet connector, might be for trim gauge. 3rd pic and 5th pic --- you should have a fuel line between the tank and fuel filter, it looks like you have 2 fuel lines, do you have an extra filter mounted somewhere? 4th pic ----- metal bracket helps hold the gear lube bottle in place and the plastic piece is a cover for the starter slave solenoid.
