Injector wire order?

Hello all, I bought my 89 Iroc Z28 from a kid that had stripped the top end of the engine down and didnt lable any of the wires coming off the engine so my question is. Is the 305 TPI a batch fire or sequential firing order and how do I know which wire plugs into which fuel injector? Any help would be greatly appreciated!

Strictly batch fire.

Doesn't matter which plug goes to which injector.

This is true, but I was wondering if there would be any benefit to having all the cylinders that fire on the same stroke to have their injectors fire together versus the right and left bank. Or do all 8 fire at the same time?
