I installed a Schuck 130X thumb throttle (from Amazon) on my Lectric XP step thru v1.0. I showed the Error Code E008 (Throttle Fault). After looking at many related threads, I reversed the red and black wires from the throttle. This resulted in an Error Code E011 (Display Communication Send Failure). This thumb drive uses the same "SM-3Y" connector that is on the twist throttle that came with the bike. According to Schuck, when you look at the male connector with the locating pin in the north direction, the south male pin is negative, northwest male pin is +5 volts and northeast male pin is the speed signal. Can anyone advise how to install the thumb throttle without error codes.
