Note: KT controller just only compatible with KT display(same communication protocol) .
Please make sure that your system is KT system.
Waterproof connector is special that I can't promise you it can 100% compatible(because of the line sequance).
But most can use it if you check carefully.
Please check your motor cable if it is Julet or Higo 9pin waterproof plug(there is some letters on the connector ).
Julet is better.But for 250W 350W 500W.Higo is also OK. Package Inclueded: 1 X Controller
