And i cant figure out which wire is positive or negitive. there is a white marking on one side of the stock coil and i cant tell if that means positive or negitive either. And also all i have to do to install the new MSD coil is plug the correct wires in and im done right? thanks guys

if its not marked, just stick a multimeter to one of the wires and test it
