Since you have the kit there, you'd need to tell us what connects to that plug for us to tell you what it *might* be for.
Regarding the manufacturer, this is Matteo Spaggiari, the founder of Bikee Bike:

if you'd like to try to communicate with him here on ES.
Here is another thread that discusses issues with the company:

Here is a link from PilotEngineer (Matteo, above) for the manual:

it will also be attached to this post once I can get the internet to work well enough to finish the upload.

Another controller's outside of my affordability.
Are you willing to open things up and do some measurements with a multimeter? (even one of the cheap ones that's sometimes free with coupon from harbor freight)
Alternately, you could just get a generic brushless sensorless motor controller, which is cheaper than their extension cable by far, and wire it up to the motor, PAS, and throttle, in place of the original.
We'd just need to know more about the connections you have available on motor, PAS, and throttle, and what you need the system to do for you, to help determine which controller would be a good replacement for you.
Is teh PAS a separate thing from the unit, or is it built into the module? Is it just a cadence PAS, or is it torque-based? If the PAS is built into the unit, then it could easily be a problem with that or it's wiring causing the motor to run without throttle connected.
Have you actualy tried the unit without the throttle connected?
BTW, you may also want to create a thread in Vendor Relations Corner about your entire experience, step by step, with the Bikee company, so that others can be pointed there whenever they indicate an interest in their stuff.
Also, you show this picture with three unconnected wires. What do those go to? If there are unconnected wires, they could easily be the entire reason it is not working. Were they in this condition when the kit was received? Or modified after you received it?
