Wiring, firing order, cylinders?

  • 3.6L
  • 6 CYL

I don’t know how or the coil pack lines up with the wiring harness, trying to put it all back together, I have numbers for 11, 11, 12, 13, 15, 15.
Do you
have the same problem?

Usually they will be real close to the correct coil if the harness is intact however it's not hard to put them on correctly if you look at each connector on bank one (1, 3.5) you will see that all of the wires in each connector are the same pattern of colors except for one wire, that wire color can tell you which coil it goes to.
So, you have the coil and the plug wire, then the electrical connector for say cylinder 1
In that connector you have 4 wires, A black wire which is the ground for the coil and the same color in all the other coil connectors, then there is the power feed to all the coils, which is the violet with dark blue trace. There is a wire that goes back to the PCM as a ground and sense feed to the PCM, on bank 1 that wire is black with a blue stripe on bank 2 it is black with a gray stripe. Does the same thing on both sides. Last is the trigger wire for the coil, this is the wire that is different for each coil and sends the pulse from the PCM to trigger the coil.
For Cylinder 1 it is blue with violet stripe
Cylinder 3 is green with blue stripe
Cylinder 5 is blue with gray stripe
Cylinder 2 is blue with white stripe
Cylinder 4 is yellow with blue stripe
and Cylinder 6 is brown with blue stripe
Apply a bit of dielectric grease to the connectors and plug them in and you should be all set.
