|I found out the contacts on my original coil pack (vertical plug) to be corroded, so I wound up getting a new one with the horizontal connector without knowing there was much difference.
As said in post #1, they definitely cannot be swapped while keeping the same firing order. The truck will not run. The vertical coil pack I've found is for the 3.0 engine and the horizontal is for the 4.0 engine. They are also used on other non-ranger engines but I don't know which ones for sure.
I am using that coil pack now by swapping the outside wires end for end, keeping them on their respective banks. The two wires being swapped explains why the documentation I could find says the 4.0 and 3.0 have the same firing order and plug wire location, but oddly the packs themselves are different for reasons unknown.
I find it odd that the coil packs are in fact not directly interchangable, despite them being listed as such on sites like Rockauto.
