I have a 1971 Chevelle and I switched from regular dash to round style. My motor starts but thats about it. When I plug in the clip for turn signals and lights and such the left turn signal comes on and wont shut off. When I hit the brakes the left turn signal just comes on and doesn't blink. I am really sad and I can't figure this out. This is all I need to fix to finally be on the road.
