Mercane Wide Wheel Pro throttle upgrade

Original Wide Wheel Pro throttle has annoyingly instant acceleration making it nearly impossible to drive slowly or accelerate mildly. In this video, I experiment with a third-party throttle connected to the Wide Wheel Pro scooter.
UPDATE: I've played with the throttle a bit and it wouldn't go to full speed (it has lower voltage on the signal pin), so I'm removing the link to vendor.
UPDATE 2: This throttle does go full speed, but you'll have to resolder connector:
