Hi Scott,

Without looking, I think that leads to the CKP sensor and circuit. It's in the left side of the block usually behind the starter, the CMP is under the VP44 pump. If you can, scope the signal to verify it's bad - most of the time I find it is the sensor and not a connection.

If it doesn't break when you try to pull it out go buy a lottery ticket, when it does break don't try to short change it, just drop the oil pan and knock it out with a punch.

good luck - you already changed the hard one!
It's a machine, not a werewolf.
