Hall sensor?

Trying out a new controller, SW900 with matching brainpower controller.
When I hook up power display and motor as per instructions I get error 07 (Hall sensor) The bike is a funhang EB-S1 500w motor
Seems like the standard set up, 9 pin juliet for phase and hall sensor. Current controller has no connector for those just the juliet connector coming from the controller, new one has separate plug for these, which seems rather cheap, maybe it's this?...bike works fine with original controller, so hall sensors are fine. Suggestions? I'm at a loss here.
Forgot to add something here, with the learning line connected, the motor surges when I power it up, when it's disconnected, nothing happens, not sure if this helps...
