2001 GMC Yukon Denali 6.0 My schematic doesn't show the oil pressure sender or its wiring. Any help would be appreciated.

It goes straight to the gauge, doesn't have anything to do with the PCM.

Thank you, you're absolutely correct. The IP schematic does show that. I was looking at the engine control circuits. The 05 harness I used on the first one I did had it in the engine controls and the ECM would shut the fuel pump down after a few seconds if it didn't see oil pressure.
I'm learning more and more as I do each one. Thanks again!
