I have a Greddy Full-Auto timer on my 03' WRX which came with the car. When I go to turn off the car, it starts the countdown and all but when the timer turns off, hte car continues to run. The handbrake feature also works, but only the unit turns off, not the engine. The only way I can get the engine to turn off is by unplugging the blakc harness in the back with the four wires coming out of it. Also, it doesn't recognize that the key has been removed unless it is in ig mode, although I've tried in acc mode as well and it doesn't even start the countdown. Does anyone have any idea of what I should do?
