I am looking at installing a set of "triple gauges" for my '64 305E. I would like to keep the factory gauges/idiot lights in place. Is there a way to run both? I can only find one spot for a coolant temp sensor, does anyone know of an alternate location? I don't suppose it's possible to run two gauges off of one sending unit. For the oil pressure, I am guessing it is underneath by the oil filter but I have not found it yet. Need to get it up on a lift. Is there a second port somewhere that I could tap into?
