Keyboard matrix

I’m looking to make a custom mainboard 13 “case” which would incorporate a mechanical keyboard. I’d like to wire the matrix directly into the touchpad connector, and according to the mainboard interface schematic under the keyboard section, I assume that KSI[0-7] are the rows, and KSO[00-15] are the columns, but it doesn’t detail which keys each row/column covers. I don’t have access to a framework keyboard so I can’t manually probe it to see which keys belong to which row and column. Are there any schematics available detailing the keyboard matrix?
