ok had finally got a minute to look at it and figure it out and reconnected my negative battery cable and my alarm went off. And it wouldnt start now. But i could hear a relay under the dash. Tore it apart and found where they like hid the alarm system and i assume the relay in it is broken cause anytime i tried anything it clicked.
Anyway unhooked all the wired and the car starts fine and no more problems, thanks guys.
