Hi
Here’s a video showing you how to replace the cable

When taking your dyson apart please make sure it is disconnected from the wall and take care when unclipping clips as these older dyson models tend to have their plastics go brittle and snap quite easily
Hopefully this helps
Any questions please ask
Thanks:-)
