Hey guys, anyone have a diagram, or can type up a list real quick, of all the A/C components for a 99 mustang?

I’m dying over here! So when I got my 99gt the previous owner did an A/C delete and got rid of everything A/C related in the engine compartment.

Trying to buy all the parts and install them myself. There’s a garage near where I live that can vacuum/charge your A/C system and they only charge you for the amount of refrigerant you use.
 
In general, the AC system is made up of:

3 Lines
Liquid - Condenser to Accumulator - Should include the orifice tube and low pressure service port
Suction - Evaporator to Compressor
Discharge - Compressor to Condensor - Should include the high pressure service port and has a spot for the high pressure switch

Compressor (may require the manifold for it to hook up any lines)
Condenser (a heat exchanger that sits in front of the radiator to cool off the refrigerant)
Evaporator (a heat exchanger that sits in the dash to cool off incoming air)
Pressure Switches (hi and low, these protect the compressor from pressures out of spec)
Accumulator (also called a Dryer, it sits between the liquid line and evaporator, and captures moisture and certain impurities in the charge).


Assuming the connectors were just unplugged, that should cover it. If they were cut, you have some rewiring to do as well.
Bear in mind that you also need an oil compatible with the compressor before you charge it (the refrigerant charge also cycles oil).

Thanks for the description! I was really struggling to paint a picture cause I didn’t know how the lines connected everything together.

That should be enough to get me going, I’m sure I’ll have questions later though lol.
