Speed Sensor Installation Failure

I havent been able to find ANY bike shops in all of Southern California that will work on Bafang electrical systems on bikes that they are not dealers for.
I am attempting to install the sensor myself and am finding the "Online" suupport quite simplistic and not the same as my bike. Quite disappointed that my 15 month old Jugg Ultra Duo 3 is breaking down just three months after the warranty period. No service available on this bike. ;-(

Speed Sensor

I picked up a Speed sensor to have a spare on hand and I needed another Magnet for my second set of Wheels. Now I have 29er Street Wheels and tires Maxxis and 27.5 Carbon Wheels setup Tubless with Specialized Tires. Awesome service and I highly recommend Biktrix.
