When you open the hood, the cylinders that are closer to the radiator are cylinder 2,4.,6 starting wth cylinder 2 starting from the passenger side. Cylinders in the rear closer to the firewall are cylinder 1,3,5. 1 cylinder starting from passenger side

The coil packs will have numbers on them, go from there. And go to autozone.com, they should have a diagram on how to hook up the wires.

If it's not stamped on the intake manifold (was on older engines), pick up a Haynes or Chilton's Service Manual. It will help you out a lot when making do-it-yourself repairs. Available at most auto parts stores.

pretty tough to do that, can't imagine why you would remove them in the first place...but, you probably have the 3.1 V6, go online, you will see that the engine has no distributor, so there is no "firing order" as such, just make sure that each plug has a wire from the nearest coil pack...why did you take them off to begin with??
