No relay needed if the unit has TWO wires coming from it (this would indicate the relay is built in) witch is usually the case with viper systems. I don't have a schematic but, what I would do is this.
Once the wire is cut (the truck will not start), I then put my butt connectors on the alarm unit wires and crimp them. Then I'll put the other end of the butt connectors over the starter wires, and test the alarm to see if they are correctly hooked up. If it is not hooked the right way the truck will not start(no matter if its armed or not), I then swap the connection and re-test the alarm(the truck will only start when the unit is disarmed).
