Purchased this 3 3/8 Sports Comp tach for my classic mustang. I am aware of the quality of Autometer gauges. BUT, the tach did not register needle movement other than a blip when I applied power ON. Switches were set for V8 and the 12v lighting worked. Confirmed my signal wiring working with my original Cobalt tach. This model of Tach has white bulb lighting. I exchanged for a Sports Comp II tach that has LED lighting.
