This is how stock mpfi cars are setup such as the 88-91 crx/civic si:

looking into the engine bay on the intake manifold from left to right:
yellow, blue, red, brown,
4 3 2 1

at the ecu:
a1: brown: injector #4
a3: red: injector #3
a5: blue: injector #2
a7: yellow: injector #1

hope this can help.
also, when I did my mpfi swap, I ran the same color wire directly from the ecu to the injectors. I didn't do any cutting or splicing. I just deppined the yellow and red injector wires at the ecu and repinned the them in their correct locations. I suggest this so that there isn't any breaks in the injector wires.
