Six cylinder injector order and correct wiring?

    I read the manual but I’m having some troubles with this.
    The manual says the injection always starts on on injector injector “E” first after cam sensor signal. Manual says injector order is EFGHABCD.
    By that logic I should be using the pins for injectors EFGHAB. My logic must be flawed.
    The firing order for this straight six is 156342.
    Cylinders 6 and 3 (G and H) not getting injector signal. From this we can deduct that on a six cylinder application that injectors G and H do nothing. I think I understand the logic as far as starting with E on a 8 cylinder engine as we want to fire the injector on the intake stroke and not the power stroke.
    My question is -
    Does it still start with E on a six cylinder application? Do I want to wire the injectors like this?
    E to 3
    F to 4
    A to 2
    B to 1
    C to 5
    D to 6

    Wire the injectors ABCDEF.

    I rewired them
    D to 1
    E to 5
    F to 3
    A to 6
    B to 2
    C to 4

    I did it earlier in the morning before anybody responded.
    Seems to have fixed the problem.
