Then STOP SHOUTING, pick up the phone, and talk the problem through with the manufacturer. That's what I'd do, then I'm funny that way.

The color coding and specific control functions can differ from one brand to another regarding control wiring....You need to check the systems for compatibility...a job for a pro....

LOL! Boy-oh-boy do we need this popup on our process screens. Although I am guessing HR would go ballistic.

Wait, what? Why connect the outdoor unit to the indoor unit? The flies are bad in the outdoor unit.

Are you talking about the control communications not working correctly?

Are you using a master controller with a communications network?

If so;

The communications protocol is currently not compatible between the two systems. You must verify the protocol and configuration settings with the manufacturer of both systems.

If the two systems are capable of being configured to be compatible: It is most likely just a communications configuration issue. (Parity, Baud Rate, Start or stop bit, etc.)

If the two systems are not configurable: You should be able to utilize a protocol converter such as a MD3000 to solve the issue.

If the system is a simple hardwired system: You must identify the thermostat, air handler, and compressor wiring requirements then adapt the wiring accordingly.

If you cannot easily identify what is needed, I suggest you contact either FUJISTU or LG technical support and get their input.
