Someone has previously, done a 6v to 12v conversion on my truck. The current setup has a coil marked "for use with external resistor" with of course an external resistor. The coil on there appears to be leaking some oil. I have an MSD blaster 2 that I would like to use to replace the current coil. If I do use the MSD coil, do I still need the external resistor?
Thanks,
