I am finding it difficult to enable these switches no matter what combination of pins i use with the switches on my handlebars. Nothing i seem to do enables or disables them so they both always stay off.
By default,the controller only needs a reversing switch to change the motor direction.
FWD switch is not necessary for customers to change the direction.
If you want to use F-N-R control,you may use pin12(FWD) and pin14（REV）for this function.
Moreover you may enable three gears switch in the user program.
The pin12 and pin14 are activated by pin11 12V,not ground signal.

I can send more details about configuration and wiring diagram by email.
