Ford 5.0L F-Series/Bronco Spark Plug Wire Routing & Firing Order 1-3-7-2-6-5-4-8

This is a scan of a Ford Motor Company "Important Vehicle Information" underhood decal (bilingual English/French) for 5.0L F-Series and Bronco trucks. The label's purpose is to show the correct spark plug wire routing to prevent crossfire. It instructs the technician to route spark plug wires 1, 3, 5 & 6 as shown in the accompanying diagram, which depicts both cylinder banks (cylinders 1–4 on one bank, 5–8 on the other) and the distributor, with the wire paths and retaining clips illustrated. The bottom of the label states the engine firing order: 1-3-7-2-6-5-4-8 (repeated in French as "ORDRE D'ALLUMAGE"). The label carries Ford part/identification number F4TE-6176-AA. A reader can learn the factory firing order for the 5.0L engine in these trucks, the cylinder numbering layout, and the specific routing of plug wires 1, 3, 5 and 6 needed to avoid ignition crossfire. All warnings are duplicated in French, indicating a decal used for vehicles sold in Canada/North America.
