SOURCE: Where can I find a spark plug wiring diagram for 1997 3.1l engine
Normally the firing order will be stamped on the top of the intake manifold also the number one plug will be the front one on the drivers side of the car. On the top of the distributor cap you should see a number one that is where the number one plug wire goes follow the firing order on the manifold and go clock wise on the distributor cap
