Took a look at pswpower, and i think this kind of confirms, that their displays are compatible:Thanks. I'll need to take a closer look. The kit came with an IT4 cable, so 9 pins at the motor, then splits to 2 brake switches, throttle, and 5 pin display.

Unfortunately they don't carry separate displays in the USA warehouse, just tsdz2/8 kits.
