Need some help finding parts

My Ender 3 V3 KE has been a problem for a long time and it’s time to get it repaired.

Is there a P/N for the entire Hot End assembly that includes the motor and associated parts so I could pull this one and replace it?

The cable that runs from the extruder pcb I believe is damaged and again I just cannot find a p/n so I could replace it.

I sure would appreciate any tips and help with this.
Thanks,
Lee
