Hey everyone, just needed some help. Bought a 1978 Scout II and now I am realizing how many lines have been cut and plugged under the hood. I got the scout with its original ac compressor trashed and in a bin in the back seat so I assume a few of them if not most are various AC lines. I also am assuming some were possibly emissions but I am not 100% sure and just wanted to see if anyone could help me identify them. The scout runs fine as of now so I'm not 100% sure. I have labeled all cut or plugged lines and one electrical line in the below image. I am assuming 4 runs to the air filter, 1 and 6 I know are coolant overflow and windshield fluid but do not know where they run to for the top lines. I have checked the repair manuals as much as I can but just wanted to check with you guys. I really appreciate the help.
