Pathy dash and doors on HB

I've found a donor Pathy that I'm wanting to get the doors, full dash, seats, console, and column out of to go into my HB. What is the best route I should take on the wiring? Will the Pathy harness hook up to my HB harness? The Pathy has the newer dash (duh) and my Hb is an 86 1/2. I want the doors for the pwr windows and locks. Thanks.
