Is there a source for a new wiring harness for the driver side door?

I've had to run four new wires and now the wires to the passenger side
power window and passenger side power mirror have died.  Add that to the
speaker wires that have died and both power wires for the driver side
window and I think it's time for a new one.

If there isn't a source for a new one, does anyone have an extra?
Parting out?  Has anyone replaced this?  Is it a pain to attach the new
wires in the door?

Thanks,
