There may well be something out there that shows the results of someone already mapping out the test points, however that should also be the thing that 30 seconds and a multimeter with conductivity testing (or a plain Ohmmeter) should be able to tell you. I can not see it terribly well on that picture but it looks like you might even be able to do it visually.
