===================================================
1> Throttle switch will be used for power on/off switch - controller does not have 3 speed.
Normally Brown (low speed), White (high speed), Blue (medium speed).
Yellow plug is Battery + power (probably to read shunt between power and speed switch - blue). Be careful. Check this out.
Blue is center pole. Red will be power on. Goes to White power connector to short out and turn on power. Check this out. first. Switch shows 1.5 ohms resistance. This is probably a shunt for the amp/volt meter.
2> Throttle twist does not seem to be a resistor. Maybe Hall effect. Black (negative power), Red (+5), Green (signal).
Goes to Speed Steering Handle Black (ground), Red (+5) on controller, White (Acceleration signal).
3> Throttle now works, but when I plug in pedal assist throttle doesn't work. I think sense wire is wrong. For now leave PAS off. Bike works with throttle.
