Here are the directions. Also, I have attached an exploded view of the system. I hope it helps.

Disable the SIR system.
Disconnect the negative battery cable.
Properly drain the cooling system.
Raise and safely support the vehicle.
Detach the heater hoses from the heater core.
Carefully lower the vehicle.
Remove the instrument panel. For details, please refer to the procedure located in Body & Trim of this guide.
Remove the DERM with the attaching bracket.
Detach the heater core cover.
Unfasten the heater core mounting clamps, then remove the heater core.

To install: Position the heater core, then secure with the mounting clamps.
Attach the heater core cover.
Install the DERM with the attaching bracket.
Install the instrument panel
Raise and safely support the vehicle.
Connect the heater hoses to the core.
Carefully lower the vehicle.
Properly refill the engine cooling system and check for leaks.
Enable the SIR system.
Connect the negative battery cable, then start the engine and check for proper system operation and/or leaks.

This is the only exploded view picture I could find of the system. I hope it helps. It shows the entire system.
