Yep, after looking at it further, you have a common hot, the black (and maybe with a white stripe) wire, coming directly from the ignition switch, and the four differently colored wires back to the ecu from the injectors are for grounding them separately... sequential fuel injection.

And I just love it that they would make a black wire the hot one.
