Okay so today I smelled something looked in the floor board and there was smoke coming up. I pulled everything out and got to the ECU. It was smoking. I unhooked the battery and then the ecu let it cool and plugged it back in. Well, the car is running fine. I think maybe I had a loose harness cause I just changed the ECU. Now the lights are in the dash, to be exact its the seatbelt litht, e brake light, they wont go off. I think there might be one more on not sure. I just changed the alternator so I know its not that. Anyway, could the ECU have fried? If it did how is the car running good? I am lost thanks for any help
