How are the cylinders numbered on the 4.0 V8? For example is the first cylinder on the drivers side #1 ? Then how do they go?

Thanks,

Driver's side, going from front of vehicle to back is 1-3-5-7.

Passenger's side, going from front of vehicle to back is 2-4-6-8.

Firing order is 1-8-4-3-6-5-7-2.

Attached is the System Circuit for the Ignition System.

That is correct. Here's a figure that might help too, with wire routing.
