Pulled my engine to do a bunch of maintenance stuff, putting it back in and I can't for the life of me figure out where this plug goes. 4 pin square connector, but only 3 of the holes are pinned for blade connectors. It's right below the throttle body and is coming out of a 3 way split in the harness, one of the other connectors is the coolant temp sensor that goes on the back side of the head.
