So today I decided to change my torn up dash in my sedan. Everything went well expect I unplugged the negative and positive terminals once I had everything plugged in and back in car won't crank! Please help! The remote for the alarm does open and unlock the car and also unlocks the trunk but the windows won't go up when the key is on the ON position. Also another thing that worries me is that the stock radio wasn't working so I bought a stock one from another g35 sedan 04 I believe and it displayed weird numbers or signs I somehow think the car locked it's self due to the different radio?0.o but I'm lost on what to do :/
