Car wont go into gear and my break, and, and fuel light/gauge is on
So today after doing the vsc mod on my car and wiring the button switch up i go to turn my car on and my break light abs light and the fuel gauge is at empty and the light is on (I have 3/4 a tank). When it happened i undid the switch and just twisted the wire (pin 4 on plug A1) so the vsc mod would be "undone" but the lights are still on and it still wont go i to gear. Another thing I noticed was the my ac and heat both dont work now.
Any help on the issue would be a big help
