hi, i am getting my car back in a week, and have an msd blaster ss coil to go in it, and i was wondering if anyone has put one in a 96 lx accord that already has an external coil? i searched this forum, but only found install help for an ex with an internal coil. i believe the plug that is plugged into my stock coil has 4 wires, correct? obviously one is positive, and one is negative, but what are the other two?

 

come on, i'm sure someone out there has done this mod and can help me out...
