I've a EB 3.9L. I've noticed a slightly weird thing about the injector loom. It had the factory grey wrap on it...but...the numbers on the caps that plug onto the top of the injectors don't match

Cylinder.......Loom Plug Number

...1............................6...
...2............................3...
...3............................2...
...4............................5...
...5............................1...
...6............................4...

On a more serious note is there anyone here who acctually does know what was/is going on?
