Re: 1998 Cherokee XJ Air Con Problem
This is a great deal
<http://www.acsource.com/index.asp?PageAction=VIEWPROD&ProdID=8>
(Hope OE doesn't chop up my link!)
Those fittings are pretty darn expensive, considering that my set of gauges
cost about $100, and came with one of each, plus the manifold, gauges, and
extra long hoses too!
Most people want to feed vapor into the vapor side of the system. It takes
a little longer, but things are more tranquil that way.

Re: 1998 Cherokee XJ Air Con Problem
From a can of refrigerant:
"Can may burst and cause severe bodily injury if connected to high pressure
side of system or any part of system with a pressure higher than 170
p.s.i.g. Using only a tapping device designed for the purpose, charge into
the system only through LOW pressure side. Consult technical manual for
proper and safe charging procedure."
The blue fitting in the link below is the small one, and fits on the small
fitting, which is on the big pipe. You are right that there is no way to
screw this up, if you use one of the cheap recharge kits from your local
auto parts store, unless you turn the can upside down. :o(
