The firing order for a 1994 Ford Explorer 4.0L engine is
1-3-4-2. However, this doesn't directly translate to spark plug wire order without knowing your specific distributor cap layout. The distributor cap itself will have the numbers 1-2-3-4 printed on it, indicating where each wire should connect.
You must look at your distributor cap to determine the correct wire placement.
There's no single "spark plug wire order" without referencing the physical distributor cap. The firing order is consistent across all 4.0L engines of that year, but the distributor cap's terminal numbering is the crucial part.
