I know this is an older thread but I figured that I would post a pinout diagram for the L1121 plug on a Bafang G062 750/1000w hub motor. I have not found this anywhere and maybe it will help someone.
The hub is from a 2024 Juiced Hyperscrambler 2, that is new but I’m having an issue with power dropping to the hub under PAS only between 17-19mph. I swapped out the torque&cadence sensor unit and still have an issue. Plus the hub sounded dry so I took it apart. Figured I check the Hall effect switches while I was in there. Interestingly enough I found the axle circlip for the bearing thrust washer loose and stuck to one of the 6 magnets that triggers the Hall effect #4 switch. So that’s probably why it’s been glitchy, plus at some point it could have made its way into the stator windings and been catastrophic.
So here’s what I have for the pin outs. The two lower pins I don’t know what they go to. One is probably for temp sensor.
