I have a question that I can't seem to figure out by looking at the wiring diagrams. On my 69 Shelby GT350, I have my gauge cluster out of the car and I noticed that below the tach next to the Brake warning light and the alternator light is a low oil pressure light. It has a bulb and a wire plugging it into the circuit board. I've never seen it light up. Because the car has an oil pressure gauge in the console is this light not connected? Or do I need to figure out what's wrong. It appears that in the shop manuals I have seen two different sending units one for gauges and one for lights. This is making me believe that the light might be abandoned in favor of the gauge. Thanks in advance. Dan
