Here ya go. I just looked up the procedure on Alldata here at work. The o-tube is part of one of the lines. Here's the right up
Do not attempt to remove the fixed orifice tube. The fixed orifice tube is an integral part of the liquid line. When a new fixed orifice tube is required, a new liquid line must be installed.
However, an orifice tube replacement kit may be used instead of replacing the tube and line assembly.
Line & Tube Assembly Replacement
1. Discharge refrigerant from system.
2. Disconnect refrigerant line at condenser outlet connection.
3. Disconnect refrigerant line at the tube-O end using a wrench on each side of tube-O fittings and remove line from vehicle.
4. Route new refrigerant line, and integral fixed orifice tube, with the protective caps installed.
5. Remove protective caps and connect new refrigerant line into the system using new O-rings lubricated with refrigerant oil.
6. Leak test, evacuate and charge refrigerant system.
3. Disconnect refrigerant line at the tube-O end using a wrench on each side of tube-O fittings and remove line from vehicle.
4. Route new refrigerant line, and integral fixed orifice tube, with the protective caps installed.
5. Remove protective caps and connect new refrigerant line into the system using new O-rings lubricated with refrigerant oil.
6. Leak test, evacuate and charge refrigerant system.
Orifice Tube Replacement
1. Remove refrigerant line from vehicle as described under ``Line & Tube Assembly Replacement.''
2. Identify location of orifice tube by three indented notches or a circular depression on metal portion of tube.
3. Note angular position of ends of liquid line for assembly reference.
4. Cut a 2.5 inch section from tube at orifice tube location. Do not cut any closer than one inch from start of bend in tube.
5. Flush out two lengths of refrigerant line to remove any contaminants.
6. Lubricate O-rings with clean refrigerant oil, then assemble orifice tube kit to line. Ensure flow direction arrow points toward evaporator end of line and taper of compression rings is toward compression nut. When properly assembled, the inlet tube is positioned against the orifice tube tabs.
7. With tube hex nut secured in a vise, torque compression nuts to 65-70 ft. lbs.
8. Install liquid line using new lubricated O-rings.
9. Leak test, evacuate and charge refrigerant system.

You can get the tools from advanced or a similar store.

LOL! Sounds like a dumb-*** question, I know. I know it connects to the black cylinder at the back of the engine bay on the passenger side, but where does it end?

Man, that's an awkward feeling when you don't know what you're talking about! LOL!

Ok, so the black cylinder in the back of the engine bay is what, the accumulator? It looks like it accumulates, so I'm going to guess the little radiator-looking thing in the front is the condenser?
