What are the position numbers of ignition coil in a Lincoln ls 2005?

The firing order for a 2005 Lincoln LS's 3.0L engine (the most common engine in that year) is 1-6-5-4-3-2. However, this doesn't directly translate to ignition coil position numbers. The ignition coils are typically arranged in pairs or individually, and their physical location relative to the engine and each other varies slightly depending on the specific engine configuration.

To find the coil pack positions, you need to consult a repair manual or a diagram specific to your 2005 Lincoln LS's engine. The best source would be:

* Your owner's manual: It may have a diagram, but detailed wiring diagrams are usually in a repair manual.

* A repair manual: A Haynes or Chilton manual for your vehicle year and engine will have detailed diagrams showing the coil pack locations.

* Online resources: Sites like AutoZone, Advance Auto Parts, or others that provide repair information often have diagrams available (sometimes requiring a paid subscription).

Without a visual diagram specific to your engine, it's impossible to definitively assign numbers to the coil packs. You'll need to look at your engine bay to find the correct locations.
