Spark Plug Wires

[edgregorio]

Last weekend, I replaced the spark plugs, wires, distributor cap, and rotor. I noted which plug goes to which distributor cap post but I did not pay attention to the different lengths of spark plug wires. Are the spark plug wires interchangable? If not, does anyone have a routing diagram?

Thank you,

Ed

What year & engine are we dealing with, here.

It makes no difference what so ever which wire goes where. As long as they are away from hot manifolds or rubbing thru something from bouncing around kinda thing.

I believe you mean 4.2 l6?
If so, the firing order is 153624

In the new set of spark plug wires I purchase, the wires came in four different sizes and plug orientations. Does it matter which wire I use to connect the plugs to the distributor cap posts?

Nope. Just the best way they fit. As long as the firing order is correct, it shouldn't be a problem.

As long as the firing order is correct it just comes down to common sense routing, as @Gilaguy23 said.
Just make it clean, there are some zip-tie tricks you can use too.
