Help with controller wiring

[CookFLHX]

I was given an ebike minus a battery. The controller isn’t wired up, and I don’t have a diagram. I’ve heard you can smoke these controllers if you’re not careful wiring them. I’m hoping somebody might be able to recognize this controller or is smarter than I am and just know what they are. I’ll post pictures as well as describe the wires….

There are five connectors, and five bigger loose wires. I know the bigger wires. Battery +&-, three phases for the motor, but I’m unsure of the connectors.
1. Two wires. Blue/white stripe - black
2. Six wires. pink - brown - yellow - green/red stripe - red - black
3. Four wires. green - yellow - black - blue
4. Five wires. black - blue - green - yellow - red
5. Three wires. red - black - green


I’ve got the battery, the hall sensors, and the three phase motors wires identified.

All that needs figured out and hooked up is rhr throttlle/on-off/battery level meter assembly. It had the thumb throttle, three led lights marked empty, half, and full compete with. Red onff button. There are five wires coming from the assembly. Red - Black - white - brown - green - yellow.
I need to find the correct wires on the controller to connect these wires from the throttle assembly.

Thanks so much in advance for helping me solve this puzzle!

Hi CookFLHS,
And welcome to the forum!

In regards to the throttle connection…
I‘m a firm believer in not trusting wire colors so would recommend going to this thread to determine how they are actually terminated.
Guide to Hall Sensor Throttle operation, testing, and modification. - Electricbike.com Ebike Forum

That said, if you are adventurous and trusting of internet information this thread my help identify your throttle wires…
Help Connect Throttle to My Bike

Your throttle will require BOTH high voltage and low voltage power sources!
Extreme caution is advised here, with no guessing allowed!
Start with just the low voltage throttle sensor wires first if possible.

Wondering about a display…?

Display is probably the 5 wire bunch/bundle if the 6x is the motor sensor bundle..
If no dedicated lock wires for a key switch with no compatible display connected the 'silver box' may not turn on until display pin1 red wire and display pin 2 blue wire are connected, these are battery voltage and lock respectively in many generic controllers.
trace back to the pcb silkscreen print to check.
2 x wires could be light output voltage or reed sensor brake cut offs, or a switch lock connection.
3x wire could be pas sensor input, or if hall sensors are used the brake cut off input
