Notes:
NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with. Use DEI part 555t or 555L. *1 The drivers door is gray/black. The other doors are BLACK/ white. Both wires are in the gray 24 pin plug at the BCM. Use both wires and diode isolate each. *2 The BCM is located above the glove box. *3 On the 4 cylinder models, use PURPLE / white at the ignition module on the driver side of the motor. On the 6 cylinder models, at the ignition coils on top of the cylinder head on the drivers side of the motor, use any one of the three wires that is not pink or black. *4 Can also use BLACK/ white (+) at the BCM in the gray 24 pin plug. *5 The amplifier in under the driver side dash above the brake pedal. *6 Low beam is high current negative, must use relay. *7 The lt. green key sense wire at the steering column must see a ground during remote start to keep the "SERVICE" light from coming on.
