i dont have any old plug wires just new in the box how do i know what wire goes where? THERE IS A PAPER IN THE BOX THAT SAYS START WITH LONGEST WIRE FIRST DOES THAT MEAN IT IS NUMBER ONE HELP

k your way from the back to the front, replacing the old ones, replace ONE AT A TIME.

take two longest do the two back ones.
so on and so forth.

I have this
hope that help

dont know if they want cylinder positions, firing order, what lengths wires go where.

when you post back with what you want we can get you what you want.
