48 Volt 1000 watt controller how to connect throttle?

Hi Everybody
We just order one controller from Amazon https://www.amazon.com/Sunwin-Electric-Bicycle-Brushless-Controller/dp/B00DBM0WFC for replacing our 1000 watt 48 volt brushless front hub motor controller but all cables are different than ours, we stuck with the throttle connection, Our throttle has 3 connector (white-blue-red) (brown-gray) (yellow-green), I attached the controller wiring picture. Any help?
Thanks

My best guess for the controller:
Red = +5 Volts
Black = Ground
Blue = Signal

Our throttle has 3 connector (white-blue-red) (brown-gray) (yellow-green),

If you have more than three wires for your throttle then you have something there other than the throttle.
My best guess for the Throttle:
Red = +5 Volts
White = Ground
Blue = Signal

Your throttle must have voltage lights and PAS/on off switches or something. The controller just wants a generic throttle with no lights or switches... but maybe you can skip the extra connectors on yours and still use it.

Normal colouring is green for the battery level indicator LEDs and yellow and brown for the throttle switch. All are optional. If you want to use those things, you need to confirm that the green is battery voltage with a meter.

There's a fair chance that the electric door lock red is the ignition wire.
