Hello i bought a ebike kit last year with a 72100 sabvoton controller , i just saw that we can put variable regen , but i don't know if it the good connector i only have this 3 pin connector left but on all documentation i don't see any of this yellow brown and black cables could it be the variable connector or something else , i don't have the usb computer cable only the bluetooth one , we can't activate the variable brake frome bluetoo
th i'm waiting for the cable suppose to arrive 06/27 thx
