well im converting the 641/2 to an altenator and im also replacing the wiring harnesses. so i was wondering should i just use a wiring harness for an altenator car or what? all the other harnesses are for a 641/2 car will the later alt harness plug into this no problem? i think ill need a new regulator for the alt. are there any other changes that i need to make? if the alt harness doesnt plug into the other harness correctly what should i do about wiring up the alt? thanks.
