[Terminator] If the T-800s come from an assembly line and all look alike, why does Reese wait until it is about to kill Sarah Connor to be sure it is a terminator? Wouldn’t he recognize it by its appearance?

Maybe he has to be sure he doesn’t kill the future governor of California by mistake?

Not all T-800s have the same tissue appearance. The one sent back to kill Sarah was a T-800 model 101. Even though we don't see other models, the fact that this one is labeled indicated there would be other models of T-800. Reece was likely not familiar with model 101.
