After wiring in the remote start system and having to tap into the non factory alarm system i have decided that using the arduino as a middle man is a bad idea.  a few tests of bridging wires and trying to try and make a physical copy of what the arduino would be doing led to the car not being happy as is sparked backfired and flooded the motor with both oil and gasoline.  I will be modifying this design to be used as a mechanical control by connecting to the phones vibration motor and when the arduino senses electrical current from the phone telling the vibration motor to vibrate i will use that pulse as a trigger to rotate a motor and make a rudimentary crankshaft to depress a button on one of the remote start kits remote.  this unit will then be mounted in the trunk of the car so i can still remote start the car via text message.
