How to fix back door lock and window on 2006 Dodge Ram. Wires split in section where door closes.

Fixing design flaw on older Dodge Ram truck window and door controls. I am not a mechanic or electrician but did this on my own truck. Did this on the fly. Viewer suggested pulling door panel and B pillar cover to replace whole wire assembly with new. Sounds logical. I was doing more of a quick fix.
