Injector plug help

[Ltdnismoracer4]

I had to get new clips aka injector plugs and I'll be resoldering them to the existing wiring that is there, but my problem is that all the wires have been mixed up. I need to know after I get all the plugs soldered on, what is the easiest way to figure out what order they go in?
