Vacuum and wiring harness NEED HELP

[bowtieonly]

Need help to identify these harnesses and vacuum hose. Where does the vacuum line go and help me identify the two electrical connectors. The pic shows the wiring harness and the vacuum taped together coming out of the firewall

1st picture is for cruise control- the vacuum line is also for cruise control.

You might want to mention what year truck. (and transmission, A/C etc..) the more information the better when trying to identify wires

It appears a previous owner removed the cruise control stuff from the engine compartment -if the electrical and vacuum isn't connected to anything. Inside the cab, by the brake switch is another switch that the vacuum line connects to. (looks similar to brake switch)
