Customer: replied 7 years ago.
I have a 2003 Silverado. My oil gauge was pegging out so I bought a new gauge and cannot find where it goes.

The oil pressure sending unit is at the back of the intake manifold area on the left side. 'The connector 1 goes into the sensor.

You can reach it with out removing the intake. I posted a picture below. Connector 1 goes into it.

Thanks, XXXXX XXXXX try again. May be my hands just wont fit back there. I negnected to mention it is a Z71 does that make any difference?
As long as this is the 5.3 and not the 5.7 then that changes nothing.
