Loose ends in engine bay - need help

[NoNiLb]

I hope some of you can help shed some light on a few “loose ends” I have. I recently purchased a 1981 911SC Targa. It has 103K miles and overall is in good shape. I have deceived to work on the car myself (first time for me) and am working on updating and replacing various suspension, break and other items that will need replacing.

As I was in the process of installing the new drivers side rear shock absorber, I found five items not connected to anything. I do not believe that I pulled all of them out while doing the work but think that I pulled at least one off. The car was running fine before and I have not yet started it up until I figure this out. I am assuming the hoses are related to the vacuum and / or fuel system? Maybe some are abandoned? Here are the five items:

Green arrow - see through rubber braided hose
Blue arrow - black rubber hose
Red arrow - black fabric braided hose
Purple arrow - long white cable coming from the rear of the cabin with connector
Turquoise arrow - multiple cables with connector
Orange arrow / circle - open connector pin (I think the green arrow hose goes there ?)

Any insights would be appreciated.

Thanks
Lukas
