    They look like the EST module and knock sensor connectors to me. I can run the wire colors if you'd like.

    have the knock sensor already hooked up with the right wire, the circular plug comes out of the big 6 wire plug i am also holding in the picture, the 6 plug connector had 2 wires that went to the bulkhead connector! Yea if you wouldn't mind checking i cant find them on my diagrams.

    I just looked at my EST module and that ain't it either. I'll have a student run the electrical diagram this morning.
