2003 + Silverado's require a module for the door locks to operate. You can check to see if the BCM has the door lock wires in the BROWN plug at the BCM or the LIGHT BLUE plug at the BCM.

neutral wire is BLACK/ white on the alarm. it needs to see a ground input when remote started, what you can do is just ground it. On the other hand you can connect that wire to a switch that comes with the alarm. one side to that BLACK/ white wire and the other to ground.

you must be mistaken. when the alarm gives a negative on the green wire it gives a positive on the blue and vise versa. Its just made to interface with (+) and (-) door locks.

Yes you need your tach wire connected and programed. Or you can adjust the alarm from voltage sense
