need help on a new build

I'm new to this eBike stuff. I've wanted to electrify my bike for some time, and a couple of weeks ago I bought a group of used parts. I got two 12v SLA batteries with covers and baskets, two brake lever/switchs, a twist throttle, a front wheel BLDC and a couple of controllers which were in need of some soldering. I was kind of surprised that none of the stuff has any identifying marks, so I cannot tell what make/model any if it is. I repaired the broken wires on one of the controller boards, charged up the batteries and plugged everything together. But it didn't work. There is one connector on the controller that I can't figure out - I don't know what it does or what it should be connected to. I've looked around in this forum and others and I have found only a very few wiring diagrams. I made a diagram of the stuff I have, let me see if I can post it here.

In my sketch there is a controller which connects to a small panel with a battery/power connector, a switch and an LED; there is also a potentiometer which I suppose is a maximum speed adjustment; a connector for the throttle/brake system; a connector to the wheel/motor with 3 power and 5 control wires. There is also a 3 wire connector with red, black and blue wires. I don't know what this connector is supposed to do. I imagine that this connector is the key to making my equipment work. If anyone can tell me what to do with this connector I'd appreciate it.

Try posting to ES website with your drawing. You may have better luck there.
