someone may give me an msd box, and i'm wondering how well they work on carb cars, as far as the tach signal, on the carb car it not only drives the tach, but the fuel pump safety relay. has anyone had any problems? do they require the tach adapter? also where does the tach wire tie into the coil negative, is it at the coil or the dizzy? or does it tie in somewhere else,if i have to run the adapter, i need to interupt it
