Hy. About the diode, I read about it, the MSD instructions say that the problem with the engine not turning off is due to some older alternators having a separate Voltage regulator. The problem is the charging light, which sends voltage to the system(MSD box) after the ignition switch is turned off. The diode(supplied) is to be connected between the charge light circuit , the voltage regulator and the 12V wire, in a set up/diagram provided by MSD in the instructions. I am not at home, that is why I keep refering to the MSD instructions as not being around me, I do not have a PC at home, I use the library's or work PC.I must go, but I will bring the tech info, also available by calling MSD.
