There are various threads over the years discussing assorted controllers for repair, modification, reviews, etc, most in in the Motor technology section, but also in other subforums, that have some info about each of those controllers. Whether any of hte info applies to yours you'd have to test experimentally, keeping in mind that connecting things incorrectly can damage the controller and sometimes other parts attached to it (battery, motor, throttle, etc).
In the last week or so is one that also references and links another thread.
If there's a specific reason for what you need to know, it might help someone help you find the specific info you need to do that.
