NOTE: This vehicle is equipped with PATS (Passive Anti-Theft System). . *1 The GEM (Generic Electronic Module) is to the left of the radio. *2 The driver door trigger is yellow/black and the passenger door(s) is gray/red. Use both wires and diode isolate as shown in directfax document #1076. *3 The PCM (Powertrain Control Module) is on the top of the firewall under the hood towards the passenger side. The tachometer wire is in pin 48. Can also get tach at the ignition coil or coil pack. Use any of the tan/stripe wires. *4 The GEM in this vehicle shuts down after the doors have been locked for a certain time period, to "wake-up" the system
