"what is the purpose of the 2nd ignition wire? where would it be connected and what would happen if it is not used?" Nothing. It doesn't show a second ignition on the wiring diagram. If you tested the wire and if that doesn't show that you have a second ignition for your car then you don't need one.   You have a second starter instead. That you will need to connect. "Is there a way of checking the anti grind without actually double starting the car and possibly grinding the starter?" I don't see why you have to worry if you got the starter kill relay setup correctly in the first place. "On the Viper 791XV, how do I utilize the turbo timer?". Here's how. DEI 530T How to test: SECOND IGNTITION Second ignition will test one of two ways. It will test with the key switch in run position only, or will test just like main ignition. Like main ignition, it will never show power in the accessory position. If the second ignition shows power only in the run position then the accessory output of a remote start device may be used to power the wire. SECOND STARTER Also known as the cold start wire. As with the starter wire, it changes state only when the key switch is held in the start position, but is not connected to the starter motor. Interrupting this wire will not prevent the starter motor from spinning. This wire needs to be activated only when adding a remote start, and must be activated only while the vehicle is starting.
