I've never seen a 4.6 with a single coil pack. They all had two 4 terminal coil packs till they were replaced by individual coils on each plug. Doesn't matter whether it's a Windsor or Romeo. Changeover year varies with vehicle model, F150 was 2000. What is this engine out of? You sure it's not a 4.2 V6? If it is, it's not compatible at all.

No single coil v8 in this year range.
Slow down and think a bit more.
All the plugs on v8 are in wells on top of the heads. Two coils, 4 terminals each for each bank..
.
A v6, all plugs are exposed down on the sides of the heads along with the exhaust manifolds.. One coil; with 6 terminals.
On top of this difference, the v6 ignition is a different type. One winding feeds two cylinders that operate in pairs.. That means 3 windings for 6 cylinders. One cylinder hanging on each end of each winding. Yes it works. Both plugs spark at the same time. One cylinder is in exhaust cycle so it does not matter in the fire order.
From the factory, there was two different plugs used in the same engine at the same time. Three each due to spark polarity and wear.
Good luck.

The only engine with a single coil would have been in a very early 97 with a straight 6 (4.9L) and a distributor.
If you check any auto parts list, you won't find such an animal your describing.
How many plug wires are you seeing?
Where are the spark plugs located in the engine?
In any event, you can't use the motor if it cannot be fitted with your original coil packs.
Reason is the computer and harness is not compatible with such a coil.
Good luck.

That's true, but some can be the old body style and Titled the next year. How that gets by I don't know.
I once has a Ranger with rear brake parts from the next year up.
Obviously there was no parts listing for it like what I had..
I just happened to ask the store to look up parts for the next year and bingo!.
Good luck.

Thanks for replying with the info.
Ford has done this for at least 35 years at the end of or beginning of a model years when production of parts are not ready for the normal builds.
You see this one is likely a Car motor.
Very easy to program a PCM and make a harness for a short production runs.
The motor began as early as 1990 in the larger Ford and Mercury cars, then went to Mustangs, then to trucks.
On the reverse of this, the Explorers as late as 2002 still had the old push rod 302/5L motors just to help get rid of inventory for that motor.
What was left was bought by outside companies.
Your Romeo is a US factory build design and somewhat different than the Windsor Canadian design
Don't tell anyone but the Romeo is a little tougher engine overall for high performance...
I would say if you equip it with your Romeo ignition, it should work.
The coils and PCM don't know the difference.
Look it over good for mounting the rest of parts needed.
For emissions, you don't know if a tail pipe sample would pass like is done in Ca.
In that state they would not pass it on a visual check either way..
Good luck.
