1989 Camaro HELP

I have a 1989 I-ROC Z28 Camaro 350 5.7lt. I rebulit the engine and didn't number the fuel injectors. I looked at the wire diagram and four on one side is one color and the four on the other side are one color. My question is how do I find or test to see which injector goes where? Thanks

It doesn't matter which lead goes to which injector, it is a batch fire system.
