The first step is acquiring an A/C compressor. I limited my junkyard search to a stock compressor that came out of a '91 to '95 Wrangler or Cherokee. Compressor of those years will bolt directly into the A/C mounting bracket.
If you are buying a compressor, you will need to get an additional idler pulley, pulley bushing, bolt, and belt. The Figure 1 shows the location of the pulley (1) and bushing (2).
Figure 1
If you are using your stock A/C, you are one step ahead. But you will need to purge the A/C system of all the Freon. You will not need to buy a new belt or pulley.
The next picture is a schematic of the system. I could not get the picture any larger due to Imagestation. If you PM me with your email address, I will send you the drafted schematic in PDF format.

Figure 3 show the intake side of the compressor. (3) is the air filter. (4) is the air tool lubricator. The air filter is a crankcase filter. The air tool oiler can be bought at harbor freight.

Figure 4 shows the fitting used on the suction and discharge ports of the compressor. (5) is a 1/4" NPT elbow. (6) is a 3/4" to 1/2" NPT (female to female) fitting. (7) is a 1/2" to 1/4" NPT (male to female) fitting.

Figure 5 shows what is needed after the discharge port. I chose to mount everything to the scissor jack mount. (8) is the oil/air filter. (9) is the check valve. (10) is pressure gage. (11) is pressure sensor switch.
