I was wondering if anyone would be able to point me in the right direction as to what these 2 plugs over to the right of the diagram are for in the KA24DE engine harness (F15) and (F16), I have been searching and can't find a damn thing on them. I want to tuck my engine harness and delete plugs that are unneeded, but I don't want to delete any that I may end up needing, any help to identify these plugs is appreciated, thank you!

F15 is the EGRC solenoid, F16 is the swirl control (SCV) solenoid. See EL-107 here:
