Injector wiring

[dwhitaker]

So far as I can see all the injector plugs have the same colour wiring, and the same connector on the end. If 1/3, 2/4 or 3/6 are swapped, does it matter? I am not certain they are in the right place. Thanks.

I should say that's on a 2.9

The injectors fire as two sets of three, not individually with each firing stroke per cylinder so it would be my guess that it doesn't really matter, hence no obvious colour coding on wires. Of course I could be talking complete nonsense (not for the first time)

Anyone else who can comment?

Yes, it is indirect injection. Therefore it does not need to be sequential.

The injectors supply a mist of petroldroplets just before the inletvalves.
Who all have their individual piece of inletduct.
The mist hangs around, until each inletvalve opens, timed by the camshaft.
Thanks to the individual piece of duct, the inletvalves do not steal from each other.
First all of the individual amount of the mist is sucked in.
Then more clean air from the plenum.

And then the cycle starts again.

Even at 1200 rpm that is 0.1 s, the droplets will not even evaporate much.

Swapping 1/2/3 or 4/5/6 will make no difference to anything, they're batch fired as a bank. Assuming it fires them once per revolution then swapping between banks would have a small effect on emissions at low revs possibly. Though using the same colour wires for both banks suggests that it might not do it like that in which case it's all the same really unless you're asking the ECU about faults.
