Exclamation 1989 Suburban 2500 Unidentified Electrical wires and Vacuum hoses

Hello gentlemen I just purchased my first Burb last week and got it half way home before it stopped on the freeway due to a pinched/shorted injector wire. Anyways I rebuilt the TBI with a kit and rebuilt injectors. Now i am going through the engine and found these dangling wires and vacuum hoses. Can anyone help me identify what they are or were they should be connected? Thanks a million!

#1 has electrical tape wrapped around the end which has been cut off.
