pwr door wiring

[80streetcoupe]

I have a 1980 GMC Sierra Classic with pwr windows and door locks and the door panel speaker. The wires have broken in half at the door hinge point which is very hard to get at. The door panel is off and I pulled the boot off of the door so I could see the wiring damage. I have repaired these before on other trucks that I have owned before but soldering and using crimp on style connectors are a pain to do and use.
Is there a replacement wiring kit out there that is a remove and replace type of unit made especially for this application or do I have to make my own?
Does anyone out there have any ideas? I need my pwr winders, locks, and speaker back. Thanks for any help in advance!!
