I had my harness re worked and I have an extra plug down by the starter. I have the wide plug that goes in right above the starter but cannot find where this narrower plug goes. Could it be the oil level sensor?

This is on a 1999 LM7 5.3

Probably oil level sensor connector. Pics would help ID the function.

here is the only pic I have



its not the blue plug but the one to the right.

also, none of the injector connectors are clicking in. Is there a trick to it or are they most likely broken?

Gen III engine. A Crank sensor would be down there.

What wire colors for the connector? The CKP has a different connector, it's the same design as the cam sensor.
