Hey, i am installing an MSD Blaster 3 coil, and i need to know which wire from the stock harness is negative and which one is positive because i have to run one to the resistor and one to the coil. One wire is red with a green stripe and the other is yellow with a white stripe. Thanks!

 

Nevermind i figured it out. My car runs a whole lot smoother now in higher rpms. i didnt think id really notice this much difference. The best part was when i re-attached my battery cable and it made my really loud car alarm go off in my closed garage....it scared the **** out of me...
