well im gonna be wiring up an msd box tomorrow and i have a question. my car is an 89 that is converted to carb and it doesnt currently have a ballast resistor. im running a duraspark ignition box and distributor. i know the duraspark box is gonna be deleted after the msd install but im just wondering if i need to wire in a ballast resistor or if the msd box takes care of all that. the only wires that hook to the coil come straight out of the msd box so i wouldnt think that i would need one but maybe i do. any help would be greatly appreciated. thanks
