Replacement Controller for Bravo EVT Scooter

[ProtonPozer]

Greetings All! I have a Bravo EVT 4000e (Circa 2008) Scooter. The controller slowly died over a period of months until it would no longer work. I found this replacement controller on-line (eBay) and wondered if anyone else has ever messed with this type. It is labelled: Brushless Controller [2-mode]. It did not come with a schematic, just a few loosely-translated instructions. They are basically worthless. I have made some minor progress: The "Learn Circuit" spins the rear tire nicely, but nothing when this temporary "short circuit" is connected. I have NO throttle response. Am looking to identify someone that might be able to offer their schematic; willing to make a donation for such a rare find! Thanks for taking the time to read my sad story.

UPDATE: I replaced the potentiometer-type throttle assembly with an after-market throttle that is of the Hall Effects style. Three wires (White/Black/White). The Controller had three wires marked "Throttle" (Red/Black/Green). I did what probably most would have done: I connected Black to Black, Red to Red, and White to Green. The whole thing worked like a charm!!! Here is a sketch of what I did. Hope it can be helpful to someone else.
