When you log in, on the right side look for “diagrams” and then “components” and you will see the list of component names and where they are located.
You can use this information along side the “Connectors,” “Connector Views,” and “Harness” diagrams to figure out what is what.
I will add that the harness diagram for the engine doesn’t show the LSJ for whatever reason, but it may hall none the less as the ecotecs generally placed things in similar locations.
