I need help

I am working on a 1990 300ZX non turbo with automatic transmission. The electrical connectors in the engine compartment have been disconnected without tags. I have determined where all but two sets of the connectors go. These two sets of connectors are exactly the same except for the color of wires. They are located at the rear of the upper plenum next to the firewall.

Male plastic connectors

Black/White (Black is a shielded wire for the White wire)

Black/Red with a Loose White cover

Female plastic Connectors

Green/Black w/red stripe

White/Black

I have replaced the value cover gaskets, installed new fuel injectors and connectors.

Any help you can give is greatly appreciated.
