Technically, there isn't any "suction" on an AC system. The "low" side is usually near the receiver/dryer if your system has one. The "high" side goes directly from the compressor to the condenser and directly from the condenser to the passenger compartment. The line that goes from the passenger compartment to the compressor (with a possible diversion to the receiver/dryer) is the low side. Look for the fitting along that line. Just trace the lines and you can't go wrong.
The high pressure charging valve is located either on the high pressure line or the muffler, and the low pressure charging valve is located either on the accumulator or low pressure line.....
The fuel pressure regulator on a 1994 Jeep Grand Cherokee is part of the pump module in the fuel tank.
The low side hose is the larger one coming from the a/c compressor to the a/c compressor... The high pressure charging valve is located either on the high pressure line or the muffler, and the low pressure charging valve is located either on the accumulator or low pressure line.

Itis located on the throttle body . It will be on the back of it..at the bottom. It has a 4 prong connector.
On my brother's 1995 Jeep Cherokee, as well as my 1992 Jeep Cherokee (Both with the 4.0L engine) the OBD1 connector is located in the engine compartment on the left side, between the air cleaner and the computer module. It's a funny looking plug, not the standard OBD connector.
It is part of the fuel pump module, it is located in the tank.
A 1992 Jeep is obd 1, not 2. The connector is under the hood, near the battery.
The 1988 Jeep Cherokee air conditioning low pressure port is located on the air conditioning compressor. The low pressure port will be on the right hand side of the compressor.
There should be a connector behind the Powertrain Control Module. The PCM is located on the right hand side above the fender well, when looking at the engine bay. It is a square connector that a DRB II code reader plugs into.
The fuel pressure regulator is part of the fuel pump. It is inside the fuel tank.
It is located under the dash on the passenger side. The blower is located on the right side and has a two wire connector, the resistor is to the left of the blower. It is held by two screws, and has a four pin connector. Disconnect the connector, unscrew the two screws, and the resistor drops out.
