How do you rewire a 1989 Lincoln town car that has had its battery connected backwards?

All you can do is start with the stuff that still works, and replace the stuff that was fried by the reverse polarity. Start with the alternator. Most likely the diode plate is useless. Next see if the igniton system works at all. If it starts, consider yourself lucky. If not, see if you can find a way to test the individual components.
Typically, you will only have problems with devices that contain transistors or diodes. Bulbs, coils, motors and other simple electrical devices are typically not affected.
Reversing battery polarity can be a very expensive mistake.
