It's not necessary on a Viper ER, since turning on the key will activate the servo. On a no-battery Viper, you need a special cable (Bender part number PVT001 for example ) that connects to an external 12-volt source and plugs into the harness under the right-side kick panel. That will activate the servo so you can adjust it.

Start the engine and lower the idle down to around 900rpms and you will see the servo motor open the valves. Then just mark where it is and adjust the valves.
