You see the wire colors for the coil pack, if that's what your asking? The red wire should be primary voltage to coil pack, the other three wires are grounds for the coil, coils, a b c, one coil fires two plugs. I looked at info for 4.2L engine.
Looking under the hood, fwd, the rear bank of cylinders from left to right, 1 2 3.
The front bank of cylinders from left to right, 4 5 6.
Hope this helps.

Check to see if the PCM or it's connector is getting wet. Where Ford located the PCM on the Freestar Vans it was the worst posible place to put them. Ford knows of the problem with them getting wet but will not fix them. If the rubber gasket on the passinger side is not sealed tight to the windsheild then watter can run down off of the windsheild and into the PCM. Once this gets wet it will cause all kinds of problems until it dries out again. Then it will run fine until you wash it or it rains or snows. Check that rubber seal first then you can look at Fords TSB concerning the problem and how to fix it. (didn't work real well on mine) Then get some aquarium sealent and glue that little rubber strip to the glass (this fixed mine). Of coarse Ford charged me $800 for their fix.

these engines did have some exh valve issues, service bulletin 05-26-3. one other thing to verify is that the cam synronizer (CMP) is correctly installed. if its not right on, its way off.

Don't need a diagram for that!
Just follow any of the spark plug wires, one end goes to the spark plug and the other to the coil.
Good Luck.
