The 235 I recently purchased came with a NAPA Ichlin IC-12 coil. Says "12v use with external resistor" and “use external resistor” on the side. The PO had converted his truck to 12V and I will do the same. I just want to confirm this is the correct coil to be using. If not, what should I purchase?

Thanks
