I have a 81 Cutlass and my Check Engine and Brake Light stays on when I start the car, I had a 350 dropped into the car and I notice there is a lot of wires that aren't hooked up because it used to be a 6 cycl, what should I do so the check engine light goes off? As for the brakes, the car stops fine but what should I check so the brake light goes off? (P.S. The emergency brake is unhooked, would that make the brake light turn on?)
