It's an 84 Mustang GT factory correct 5.0
Its okay, The schematic aint always so easy, because the names of the parts evolved from the 1979 list.
They are noramlly color coded Pink or Blue or Orange, but can look Purple or Brown with age (or I might just be a closet color blind guy...)
Part number 12A 182 makes it one of the VCS Vacuum Controlled Switches (actualy SOL V Solenoid Valve operation switches).
The Best swap-over was Red 78''s original 1979 list
http://myzephyrs.com/vac_part_name.htm
Vacuum Controlled Switch (Generic)
Vacuum Controlled Switch (Cold Temp) = VCS-CT
Vacuum Controlled Switch (Decel Idle) = VCS-DI
Manual 4-bbl 5.0 83, 84 and 85's differ, so these two 85 diagrams will only be a little help.
I think 1984 5 speeds had four
Its the multiple terms for the same thing....
I've found this the nicest quick list care of qikgts
Its a Solenoid operation device, what it operates is labelled somewhere else with a letter on the schematic.
Problem here is that there are incorrect terms on the VECI diagram compared to the 1979 list. Sometimes, the line diagrams have your eye balls on hellz-apopin' stalks after a few minutes.
SOL V DIV is the TAD vent Solenoid, Diverter
SOL V DUMP is the TAB vent Solenoid, Bypass
On other engines, it has a different colors, and sometimes, a different purpose.
Now, AIR: This is a Secondary air injection Ford calls the Thermactor, short for Thermal Reactor. CA vehicles are installed with it as standard. Air Injection Reaction is what it stands for.
The thermactor system consists mainly of the air pump, the air pump diverter and bypass valves, TAB and TAD solenoids (if equipped) and the catalytic converter.
AIR BPV: Air Bypass Valve (aka Thermactor Air Bypass TAB)

In detail
Thermactor Air Bypass Valve
(TAB or (BPV) /AIR Bypass (AIRB) valve
ACV (Air Control Valve) is the TAD (Thermactor Air Diverter) Valve
(AIR Bypass (AIRB) and AIR Diverter (AIRD) valve combinations)
MAN VAC is Manifold Vacuum
FPR is Fuel Pressure Regulator
EGR is Exhaust Gas Re-circulation Valve
SOL V: Thermactor Air Diverter (TAD) Solenoid (SOL V) (AIRD) & Thermactor Air Bypass (TAB) Solenoid EVR is EGR Vacuum Regulator VRESER is the Vacuum Reservoir Can (Tank);
V REST on later years is Vapor Valve (Roll-Over)
V REST on earlier years is a Vacuum Restictor/delay valve, it delays vacuum for a certain amount of time
Carbon Can is Carbon Canister (Charcoal Canister, Vapor Canister, Evaporative Emission (EVAP) Canister)
MAP is Manifold Absolute Pressure Sensor
AIR BPV is the AIR Bypass (AIRB) Valve; also called the TAB (Thermactor Air Bypass) Valve
CPRV is Canister Purge Solenoid Valve/ Canister Purge Solenoid (CANP)
VCKV is Vacuum Check Valve
CAT is catalytic converter
ENG is engine
PCV is Positive Crankcase Ventilation Valve

Try this....it doesn't have the colors, but its 5 spped 5.0 4V GT 1984!
Isolate what VSC you have, and check the lines to match.
You might have various other lines to the Upshift indicator switch.
These are 1985 5 speeds, and might be different to your 84, but this WILL give you a great head start.

I think the hard tube is the hood release cable
This is a CA car and it's not the hood release it's definitely a hard vacuum tube that broke when I tore down the top of the motor
