I got my 71 over 20 years ago it had been hit in the front and took me over 10 years to get it back on the road. Before I got it the car it had been switched from auto to 5 speed. There are lots of unconnected wires around the coil. I noticed in my repair manuals a green wire from the negative side of the coil going to a speed relay and revolution relay. Is one of these involved with the tach? Can I run a wire from the negative side of the coil straight to the tach? Any ideas would be appreciated. I have a 73 auto but the setup does not look quite the same. I have switched instrument clusters before.
