On your smart phones browser put in Make, model, 3.2 engine firing order. It will bring back the firing order sequence and from that you should be able to figure out the wiring sequence and which wire goes to which plug. All you need to know is where the number one plug is on the coil pack.

Firing order is 1-2-3-4-5-6 , engine numbering is 1-3-5 towards the back and up front is 2-4-6, coil numbering from left to right is 1-4, 6-3, 2-5. This is for your year of engine I hope this helps you!

Look on the intake manifold often the cylinder order is marked on it.Then plug in the proper coil wire.

Try this firing order sequence and see if everything is as seen here.
Firing Order:
1-2-3-4-5-6

Cylinders:
........(back).......
'...1....3....5...'
______________
'...2....4....6...'

Ignition Coil:
.......(back)
.....connection

..........V

2........4........6
.......(front)

cylinder firing order on 1999 mercury V-6 engine is 1,2,3 on the passenger side starting from front to back. on drivers side engine cylinder is numbered 4,5,6 starting from front to back.of course you already know the distributor firing order sequence.

The best way would be to obtain a firing order diagram and go by that. You can probably look at the diagram somewhere online for nothing. Crossed wires are a pain to guess at.

1,4/6,3/2,5 Orginal coils should be marked if not first coil is always left side of module if you are lookimg straight at it,

cylinder 1 is on passenger side, coils should be numbered, cylinder 4 is on drivers side

I guess as you may know , it has indidvidual coil packs for each cylinder. The ones on the driverside, 4,5, and 6 are easy to change. just unscrew the bolt holding the coil pack down on the plug and pull it off and unplug the coil pack from the locking plug by squeezing near the back where the wire goes in the plug. The ones on the passenger side require removing the intake manifold to get to them. This is not as hard as it may seem but the wires and a bracket connected in the back of the manifold do need to be disconnected in order to free the manifold for access to the coil packs. Wasnt such a hard job but a bit of a challenge.
