A logic probe ( led, resistor, batteries in series with 2 wires ) can tell you what you want to know , providing there is no IC chip in the keyboard, may not have same success with touch pad if that is on the ribbon too,
keyboards use a matrix to encode, so going by ians example , if we have 17x6 pins, then when you apply power to one of the 17 pins, and press a key you will get volts(led will light) on one of the 6 "outputs"
so your key map will look something like this:
g= (11,1)
h=(11,2)
i=(12,1)
j=(12,2)
this is just an example...
