Ok guys, I recently bought my first stang. I have some questions regarding my gauges. Here goes.... 1. My temperature gauge in my orginal cluster doesnt work. How do I restore it? 2. I do have a set of aftermarket VDO gauges circa 1988 or so (was the shyt back in those days). The first gauge is a vacuum gauge. It reads a steady 20 psi on idle. But what is this really for? The secound is an oil pressure gauge which shows the pressure to be about 15 - 20 psi above the stock one in the original cluster. The 3rd is a Transmission temperature gauge. Is it possible that my orginal equipment has been rerouted to the T5's temperature instead of my engine's coolant temperature? What should I do with these gauges? Leave them? How do I fix the coolant temp gauge?
