Has anyone installed a Viper remote start or alarm in their pmc? I am attempting a Viper DS4 remote start utilizing a Directed T-harness model THCHN3. The harness has two basic connections - the OBD2 port and the ignition connector. It appears the ignition connector on the harness does not match the connector that plugs into the actual ignition harness (below the key). I contacted the manufacture and they said it's the correct harness. Any suggestions?
