How do I find the #4 fuel injector on 2005 town and country?

What size Engine?
The Number 4 fuel injector goes to Cylinder #4.
On 3.3L and 3.8L it should be the Front Middle Cylinder.
If you are not sure where Cylinder #4 is. Look on your Electronic Ingition Coil = Distributor. It has small numbers on them #1 thru #6. The numbers are small and black, but they are there. Follow that #4 wire to Cylinder #4. Fuel Injector #4 should be right over the top of that Cylinder. Usually the Cylinders themselves have numbers on them on the engine block, but it is easier for use to use the Ignition Coil as a reference.
Cylinders Numbers should be:
1 - 3 - 5 Rear
2 - 4 - 6 Front
Ignition Coil should be:
6 - 3 Rear
4 - 1 Middle
2 - 5
