Need some help. I have got some boost, oil temp and oil pressure delfi gagues, Think I have figured out how to wire the gagues up on how they work, ( live, earth, ignition lve etc) But I'm wondering what other people have used for the ignition live? Also I am struggling on where I am going to plumb in my temp and pressure sensors? I'm guessing pressure just replaces the pressure switch? But then what do I do with the engine loom wiring for the original sensor? Because surly with it unplugged the oil light will be on the dash? Also where does the oil temp sensor go? And help and advice will be great thanks . Jack
