Green and blue are connected to the harnesses

Red is connected to oil pressure

White is connected to the oil pan

Trying to figure out which ones go connect to together

 

The oil pressure and oil level sensors plug in to the starting/charging harness that is probably still in the car.

The green and blue are connectors that cross over from the ECU harness to the harness in the car. I think black is the water level sensor cross over connector.
