Does anyone have or can get a pic of the plug and wire color for the oil pressure fuel pump relay switch for the tbi 5.7?

Oil pressure fuel pump relay switch question

I can't get you a pic but I can tell you that most people are mistaken as to what that pressure switch is for. That switch allows the fuel pump to continue to run in the event that the fuel pump relay were to go bad as long as there is 5 psi of oil pressure.
I know what it does. I put a tbi motor in my blazer and took it all out planning on it being a rock crawler. Now my plans have changed and I want to go back to oem wiring.
