Wire harness / where to injector question....?

So I labeled everything.... and as I was re-taping the harness I laid out the four labels for the four injectors neatly on the floor and the dog messed up my lay out. ****.

So so my question is the harness comes from the passenger firewall and routes down to the pass frame rail and then sneaks between the back of the water pump and in front of the lower intake manifold.... to atop the engine block. There’s two plugs for injectors on the harness at this point and then a few inches further is another two.

Anyone have an idea how they’re plugged in...??
For instance first two for lower injectors... second set further along harness for uppers...??

THANK YOU...!!!!

It's been a while since I've seen a factory injector clip, but isn't the wire color exposed at the connector?
See wire colors for each injector below:

I’m closing in on getting everything back together. It’s taking so dammmm long bc I’m cleaning everything back to it’s original beauty. It’s pretty simple to remember from this day forward. The injector plugs w the water pump sensor plug is front rotor and shorter of the two are primary. Thanks again. I’ll post a pic just bc...
