Help identifying electrical connectors

[fredp]

During the endless job that is stripping down the car for painting, I came across 2 electrical connectors in the engine bay that don't seem to be used.

Can anyone enlighten me as to their use?

those are used, were used better say, when running the engine diagnosys tests

The diagnostic plug wiring can be removed and thrown in the can... BUT you should read and understand the wiring schematic first... an ignition critical current path runs through it, so you can't completely dispense with all of it. I learned this the hard way with one of my 2002s. I seem to have learned most of what I know, sometimes, the hard way.

Does anyone know what is the part number for the Orange port cover?
I am keen to replace the deformed one in my car.

I can find the white one in RealOEM.com (item 5):

but have no idea where the Orange one is?? :confused: I believe the 2 port covers are slightly different in shape.

Those are likely NLA but I have seen them on eBay a few times.
