I think I found the leak??

The first image is the driver side and the 2nd is the passenger. I am not sure what these are but it looks as these are what is leaking...can someone help me out and tell me what these are and I hope, I hope these are not expensive and hard to replace if this is the culprit. It is leaking so much there are drops on the ground and it just started after I did the 6.4 banjos and FPR (blue) spring...

That looks like the glow plug harness to me

Are those notorious for leaking? I cant remember reading that anywhere and would it be oil or fuel leaking from there? I tried to smell it but it has no smell and cant tell the color after it has leaked on everything

Read this.
why do glow plugs leak oil?

[CCSBD]

so after reading it doesnt seem serious and that hard to replace but would they leak pretty bad? I just ask because there is oil all over my front axel and cross member.

I wonder why it would just start being this bad after I did that work to it? I didnt even touch that harness?

This is the part number I found 5C3Z-12A690-A, is this correct?

Also does it come with both the driver side and passenger side or just one? If just one are they both the same part numbers or different?
