Question about 1987 Mercury Sable
I don't know if there is a free wiring diagram available, but to turn the engine over you will need to purchase or build a bumper switch. A bumper switch can be easy to build and relatively inexpensive. Get two gator clips and a bumper type toggle switch. Connect about three foot of wire to each side of the switch, this will create a broken circuit. Locate the ignition wire which is on the starter, since there has already been a lot of damage to your wiring, one more cut won't hurt. Clip this wire and skin it back and connect one gator clip and then connect the other gator clip to a hot battery, this will create a complete circuit. Switch the car on and push the button, it should turn the car over if the starter good. If the starter doesn't turn over then that may be your whole problem.
