...to work for my 1976 Corvette? The interior and exterior lighting went out when the RPM gauge got stuck at 5000 RPM. The headlights work but all the other lights are dead. When I step on the brake, click the turn signal, and put it in reverse, those lights come on. All the light bulbs and fuses in the fuse box are okay. Please help. I rattled my brain and I can't figure it out.
