i have a 5th gen lude.
the msd blaster coil 3 comes with a positive(+), negative(-), and the tower. and my stock coil has 3 wires and the plug that goes to the tower.
which wire is positive and negative? yellow wire, yellow w/ black wire or green wire? and what is the third wire?

If you read it, it tells you what you need to know to put in just the coil.
