You just said '80 Corolla, not "80 Corolla with 2JZRB26JDMmadtytevtecks" or whatever. You didn't say what coil it is either, MSD makes a lot of different coils, some of which require a resistor and some that don't. But put the sumbitch on, the
worst that could happen is you fry the coil and your spark module too.
