    Weatherproof Connector

    I am soldering the weatherproof connector to the BMSBATTERY controller (S06S). I understand that the larger blue , green and yellow are for the 3 phase motor wire. The smaller blue green, yellow, red (+5V) and black (GND) are for the hall sensors. There is a ninth wire - white - what is it for?

    Hydraulic cut-off brakes

    Diogic, I'm also interested to see what you come up with. Would Izeman's solution http://endless-sphere.com/forums/viewtopic.php?f=3&t=38848&start=25#p691975 satisfy TÜV's requirement of not having the switch outside the lever? It is technically inside. Chalo once suggested to use this...
