need help with my viper 300 esp

What make/model/year car is this in?

Usually viper recommends interfacing with the start wire tp prevent the car from being started. Lok at your wiring harness coming from your ignition, locate the starter wire and look for a relay connected inline. Bypass the relay by reconnecting the factory starter wires. If you dont have the relay in that spot, they may have used it to kill another component. But I would say theres probably a 90% chance that the starter is what it is connected to.
