Question 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

Instead of splicing the wires, un-pin the new connector and the old connector. Then re-pin the new connector with the old wires. Thats as long as the wires and terminals are in good condition. Just my humble opinion.
