[1999 White C5 Coupe]

After countless attempts of trying to disable the auto start stop feature. I finally found a wire and harness that works. On the advertising it list multiple GM and Chevrolet products but it does not list the impala. I installed this unit and have not had any issues with the auto stop feature.

I have driven two Ford dealer service loaners with the stop-start system. I will NEVER buy a vehicle with the system, unless it can be easily turned-off permanently in a settings screen.

Miserable idea.
