70 442 power windows wiring diagram

The power windows in my recently acquired 1970 442 are not working. Can someone point me to the proper manual that has the power window wiring diagram? I have both the 1970 CSM and A-body PIM manuals and do not find this in either of them. I wouldn't think it would be in the Fisher Body Service manual, but if that's where is is I'll buy that as well.

This will hold you over until the Fisher manual arrives.

Thanks Rodney. The wires weren't hooked up as illustrated in the fuse panel diagram. After incorrectly chasing the power door lock wires for a while I finally determined which bundle was for the power windows (after I removed the driver's door panel). I jumped the relay lead and determined that the relay was bad. New relay is on order. Next up.... trying to figure out why the tach isn't working in the tick tock tach.
