LS1 Engine Oil Pressure Sensor Wiring Colors
Does anyone has the wiring diagram for the Engine Oil Pressure sensor for a Silverado 2004 5.3?
I'm replacing the connector but it has different wiring colors
The ones that I have on the harness are black, green(olive)/white and tan/white
The new connector has these colors:
Position 1: Red
Position 2: Black
Position 3: White

Position 3: White

Tan/White = Signal circuit to PCM
Black = Low ref (Ground) to PCM
Green/White = 5 volt reference from PCM (this is typically a gray wire so maybe it’s faded or has been previously repaired.)
As long as you make sure the original wiring is on the correct pin at the terminal, the color isn’t going to matter.
Hold the connectors side by side and take a picture or draw a diagram of the wire positions in the connector to ensure it’s properly installed.
