V6 1999 ford f150 spark wires from edis to plugs how are they hooked up?

The 1999 Ford F-150 4.2L V6 uses a Distributorless Ignition System (DIS) with an Electronic Spark Distributor (EDIS) module. There's no distributor in the traditional sense. The EDIS module controls the firing order and sends the spark to the spark plug wires. There isn't a simple 1-to-1 correspondence like in a distributor system.

The firing order is crucial and getting it wrong will cause misfires or engine damage. The firing order for the 4.2L V6 in the 1999 F-150 is 1-5-3-6-2-4.

To determine the correct spark plug wire connections from the EDIS module to the spark plugs, you must consult a wiring diagram specific to your 1999 Ford F-150 4.2L V6. This diagram will show the correct wire routing from the numbered EDIS module output terminals to each cylinder's spark plug.

Where to find the wiring diagram:

* Your Owner's Manual: Check the electrical diagrams section.

* Ford's Official Website: Search their parts and service section; you might find downloadable diagrams.

* Online Repair Manuals (Haynes, Chilton, etc.): These manuals often contain detailed wiring diagrams.

* Auto Parts Store: Many auto parts stores can print out wiring diagrams for a small fee.

Warning: Improperly connecting the spark plug wires can lead to engine misfires, damage to the EDIS module, or even engine damage. If you are not comfortable working with automotive electrical systems, it's best to consult a qualified mechanic. Using a wiring diagram is absolutely essential for this task.
