Default Simple wiring questions

Question #1 - What is the pin out on a fbody crankshaft position sensor? The plug on my harness got pulled off, now I have 3 colored wires and im not sure which order they go back on the connector.

Question #2 - Im using a truck MAF with integrated IAT sensor, it has 5 wires on the connector; Red, Black with White stripe, Yellow, Orange, and Black. Which wire do I connect to which on the fbody harness connectors (MAF, and IAT)? (See attached for wires)

Question #3 - I have 1 mysterious connector on my harness that I have no idea what it goes to, maybe cruise control or something? Its not the red one but the whiteish one on the opposite side of the coil pack connector, its 2 pins, any ideas? (See the 2nd attached picture)

Question #4 (last one) - The red connector in the second picture is for the EVAP purge selenoid right? Heres the deal, that red connector goes to this black thing on the manifold of my v6 (putting an ls in my v6 camaro). What do I do with this red connector now? It has to go to something. What do I have to buy for this thing to plug into? Also the EVAP hose that runs up front with the rest of the gas lines, it plugs into the left or right side of the manifold?

Sorry for the long post put this is about all I need to finish up my swap!

Thank you! Much appreciated!

I figured the whole EVAP thing out, go GOOGLE!

Leaves only one question, what is the mysterious white colored 2 pin connector for?

that white connector you posted is for the air shutoff valve. If you deleted the air system you do not need it.

vent line plugs into the evap which is mounted to the dr side of the intake. From there the evap has a small plastic hose that goes to the driver side of the intake right behind the throttlebody

Update, I got all the wiring done tonight, Im so glad I wont have to fiddle with it anymore for this project.

One last question, How does the EVAP solenoid mount, I cant find anywhere to put it? Not sure if it matters but im using truck coils and brackets.
