1g spark plug wiring order

Here is a diagram showing how to route the spark plug wires from the coil pack to the cylinders.

Special thanks to femmeDSM for making this diagram.

This is the spark plug wiring order, not the firing order which is 1-3-4-2 on all 4G63's. If you don't know the difference between the two, go directly to jail, do not pass go.

The diagram does show the correct relative positions of the cylinders and coil towers but fails to show the correct spark plug wire routing which is designed to keep the wires from inducing spark in the wrong cylinders by separating the wire for 1 and 4 from 2 and 3.
