So I am doing a rebuild on my turbo, and was disconneting the ecm, I noticed that the pins on the big connector which if we looking at it from front of engine is the first ecm plug. It has 5 big pins, and I noticed that 2 of those pins were raised higher than all the others.

Is this by design or have these come loose from the body.

Is there anyway to check that they properly connected to circuit board.
