I know I'm getting off the subject now about his question, but this got me looking at both haynes manuals now. It doesn't show anything in the one for the nissan I have for oil pressure switch in the electrical diagrams, or even in the index does it mention the words oil pressure like it does for my buick. Is there a way to add a pressure switch to the engine somehow if it doesn't come with one? Should there already be a plug somewhere that I can take out and add in a pressure switch or would you have to drill through and thread somewhere? It's a 95 sentra.
