Advice on where to get a new 48v 1000w controller

[Redfoot247]

I need to source a new controller to upgrade an existing e-bike kit.
Does anyone know where I can source a 48v 1000w controller, with the wiring to install a screen (sw900 - 5 cables) and hand grip throttle (3 cables)?
I’ve been trawling eBay and Amazon but not yet found any.

Looking for a generic controller. It’s a home build. Currently on a cheap controller with no screen and a thumb throttle, but the user finds the 1000w hub too fast on the pas and wants to be able to configure the pas.
I reckoned easiest would be to change the controller to install a spare sw900 and twist grip throttle, but struggling to find a controller with the five control cables for the screen?

Not really.....I’m looking for just the controller. I’ve got plenty of spares of accessories.
Trouble with this brand is establishing that it has 5 wires to the controller inside that waterproof connector?
