can someone tell me what i broke

[CHEECH]

I was doing the egr delete per the wite up thats posted in the forums and somehow managed to break one of the connectors that go into the inside of the head , there are 8 of them. the connections from the wireing harness has a horseshoe type clip that holds them on the connections going into the head
what are these and how do i replace them? any input is appreciated,thanks

It's an injector plug, Depending on what you broke you can either replace the harness or the injector.
