Default Merc. gen 6 502 injector wire sequence

I am confused on what injector plugs go to which cylinder? I have pulled some wire diagrams and my wiring colors don’t seem to match up. I attached a few pictures if anyone know what plugs go to which cylinder that would be great.

I thought they were batch fired and followed what would be carburetor intake pattern, I know it's MPI.
1,7,4,6 for one color. 2,8,3,5 for the other. ??

They are batch fired, and so far as when, according to articfriends (smitty) it makes no difference when each one is being fired. The list above is for the Gen V block and the Gen VI is how you have it listed

Dodge has it right and they are batch fired or some even call it bank to bank as well. There is 2 injector drivers inside the ecm and the injector driver fires 1 4 6 7 and the other injector driver fires 2 3 5 8. But that does not hold true for the L 29 454 and 350 HO mag that fires differently the injectors -- it still is batched fired thou

Again Dodge has it correct in the lay out. exactly
