I got a msd dis-4 system for under 100 so i went for it, i was reading into it more and i am wondering if it is possible to hook this up to a 99gt mustang ignition. If it is not possible does anyone know why, also how hard is it to convert my car car to a twin coil pack ignition, such as the 97? style. as you can tell im not to pos. on what im talking about my ignition confuses the hell outta me, i know its c.o.p. n its a pain in the a** thats about it.
