Polecat,
It's in the back of the service manual under accessories section 9-97, or page 1389 (I'm quoting the 1978 manual).
Also, in an other post, heed the advice of the poster and run a ground wire from one of the motor fasteners through the boot and into the under dash, then find a suitable place to fasten the wire for ground.
I'll check to see if I have any spare boots...I might but if I do, they have the wires to the motor included.
stwrangler, be careful when pulling the wires out of the boot. It's very tight and you'll pull the connectors off. Polecat, you might have to find those wires and boots together on a ebay auction. They're very hard to get out of the boot without damage.
Also, Polecat, I copied a thread on how to install the power window regulators on a non power window door from the TAC forum...before it crashed. PM me your email address if you want that document.
