They're not specifically documented in one single place yet, unfortunately. I want to eventually make a nice post with all that info. But for now, you should be able to find information about all signals the cluster takes. A couple are documented in this thread, the rest are scattered around in various threads. Use the search function to search for the line you're interested in, like MTRTW, METSCI, etc.
Here is the cluster wiring diagram I made for myself, taken out of the service manuals. It has the names of all the signals:
You can find the manuals here:
If you're interested in a specific signal and you can't find info on it, just ask me and I'll be happy to help.
