Welcome to the forum.
The seats will bolt in directly as a replacement. As for the electrical you'll probably need to do a little of your own. What's nice is the heat module for each seat is with the seat and not elsewhere. The switch is on the seat itself. You'd be wise to get the connector in the wrecked 'Bu by cutting it out of the car. You can use the following link to my DropBox account to see the schematics for the entire car. Power seats are there as well.

You're about 6 or 7 hours from here. If you need some help we can make arrangements for me to show up. Gas, meals, parts. As cheap as we can make it for you, and I solder all of my connections and use heat shrink. Take a look at one or more of my How-To links to see.
