Identifying injector wires

I just got done replacing eight injectors in an 86 IROC TPI but I make the mistake and forgot to mark the injector wires before I took them off. Is there any way to identify which wire goes to what cylinder?

Doesn't matter at all on TPI systems. So don't worry.

Tuned Port Injection is a batch fire system. It would be a big mistake to mix up wires on a Sequential Port Injection system, but on TPI since all the injectors fire at once... get my point?
