Okay. I think I see what you mean.
For info on what wire is connected to what at the other end, we need to look at the info for the air conditioner at that end and the thermostat at the other end.
How each is connected, depends on who made the parts at each end, as builders do not have a "standard " in many of these cases.
This is an example of a Dometic thermostat wired to work a Dometic AC unit but that will depend on what and who made what you have, so may/may not apply.

Since there are many different AC and thermostat builders, and they have not fully agreed on a standard they each build different things into their item, so we can't point to any one specific drawing which might fit your specific setup.
The only way I know to sort the problem is to start with finding wiring for the AC unit and the thermostat to try to meld them together.
