If you want to interrupt the starter circuit, look at the connector at the ignition switch. Remove the steering column upper and lower shrouds. Pin #13 Yellow wire is the starter relay circuit. If you connect here and arm the alarm this will disable the starter relay from operating.I'm trying to install a Viper alarm in my truck but can't find a good ignition wiring diagram. I'm just using the ignition/starter interrupt but I don't know which wire under the dash to cut. Any help with diagrams or experience would be great!
