This may or may not belong in 3L, but I think that the most likely folks to try this have purchased a 2004 or 2005 motor with COP and want to keep it.
Disclaimer: This requires basic wiring skills and is best if soldered. Also, controversy (without much real data either way) exists about the benefits and risks of using COP. I drew this as a combo schematic and formatic drwg to make it easy to understand routing. I did mine on the motor to keep my mind clear about what went where.
I won't get too deep into how our ignition works, but everyone should know that their coil has 4 input wires: 12V power, and 3 inputs to fire the 6 coils. 2 cylinders are paired together, so when one fires, so does the other, thus one spark occurs at a useless point in the combustion cycle and is "wasted", so our ignition system is a "waste spark" system (if you know all this great, some folks don't). The pairing is 3/4, 2/6 and 1/5. All of this can be seen in your Haynes Manual or Ford CD.
To run COP we must supply the same 12V for power to each pair, and the same signal to each pair that they get with the coil system. The following picture shows how 12V is spread out to the input side of cylinders 1,2,3 and their output becomes the input for cylinders 4,5,6. The other or output side of 4,5,6 are connected to their respective signals (c1, c2, c3 as shown). This works really well if you get a Taurus motor with COP installed, you have all the wire you need, just needs some re-routing. You certainly can make one from scratch, it will take longer.
Hope this helps, ask questions about what's not clear.
