Mystery Hose (at least to me)!

[theslawdawg]

Hello Everyone,

I am a proud new member of this forum and a new owner of a great '72 Cheyenne that I acquired for dirt cheap. I am not great with engines but I'm trying to learn. I have some questions that I hope someone can answer. I have attached some photos of a hose that I found not attached. I have no idea where the loose end is suppose to attach to or what the end that is connected is attached to does. The last photo in the bottom left area has a cylinder that had an electrical type connection that was not attached. I attached it but I have no idea what it does. The truck was running great prior to me connecting it and has been running great after I connected it. It also has been running fine with the open hose.

Also, my windshield wipers work great but my windshield fluid components refuses to work. I can hear the fluid motor going when I push in on the windshield wiper button (if that's what I'm suppose to do to make it work) but no washer fluid gets sprayed (Yes, there is washer fluid in the tank!).

Finally, I'm trying to replace the locks on the doors. How the heck do you get the handles (door and window) off the side panels without breaking stuff?

Thanks in advance for any help and have a great Christmas!
