If you wire it like Dick recommended, you also need to use the 3rd pole (set of contacts) which is probably a normally-off (i.e. when the other poles are on, this one will be off), to hook a power resistor to ground so when you disconnect the alternator and kill the battery power the energy from the alternator has a place to go until it stops spinning.

I have read before about using a resistor to protect the alternator but at least on the 3 or 4 Rx7s I have wired this way I have never had an alternator problem. I don’t know if some systems are more fragile than others.
