thank you I see what your talking about,but the one connected to the one from under the manifold I’d connected to a black connector which I will change tomorrow,that leaves the black connector ? Also I have the hose from under the manifold that was leaking coolant (replaced) ,I know it goes to the front of the engine but I don’ t see where
 
Without a picture this is only a guess, but I think the black connector is for the power steering pressure switch. It should have white and brown wires in the connector.

Before I can help you, I need pictures of the black connector and the hose you are talking about.

I went through the wires that I connected are correct that grey plug has brown with white strip and a white with a brown stripe ,the head temp has a red wire and a black wire

The Grey connector has a brown/white and a white/Purple wire is for the Cylinder Head Temperature sensor.
The other Grey connector that is missing with the same color wires comes out of the bottom front of the intake manifold near the coolant hose that was replaced.

My guess is that the connector is under the intake manifold somewhere or laying on the side somewhere. 20230808_154720.jpg
Look at the picture were I'm pointing at the wires.

You mentioned a black connector, I believe the knock sensors has a black connector also under the intake manifold.
Connector Black C108 in the above post.
You have to match Grey with Grey and black with black.
By the way the plug or connector without a mate is a female. ?

I found it ,took bolts out propped it up stuck my hand in there and found it kinda drove me nuts ,but the worst part is ford put the coolant line ,nock sensors ,and the temp sensor under the manifold,hell
why didn’t they put the throttle body inside the muffler .ya wanna hide stuff go all the way !
