Cyclamatic Pro Power Plus CX3 bike problem

I'm having a problem getting information on Cyclamatic bikes. Specifically, I'd like to know where to get replacement parts, etc. I recently had the problem of my ebike not activating. When I disconnected it and reconnected it directly to the Hailong battery output, it started right up and I can use it again, but without the speedomotor function. Seems the Cyclamatic bike has a chip in the assembly guiding the brake lever lines that makes this function work. How do I get a replacement for this part, or is there another way for me to get the speedometer function working. For that matter, how does a speedo work on an ebike? I noted that the cable connecting the LCD display to that part has 6 pins, but the one I have the LCD connected to now (directly to the battery) has 5 pins.

Any info would be greatly appreciated.
