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. The passlock II wire colors are yellow, black, and RED / white (not used).  *1 The BCM (Body Control Module) is under the driver side dash.  *2 If Directed module part #456G is not available, refer to directfax document #1601.  On base model trucks the lock wire is lt. blue (-) and unlock wire is white (-). They are in the lt. blue plug at the BCM.  *3 On base model trucks the door trigger wires are in the lt. blue plug at the BCM. On 4dr trucks the LR door trigger is lt. blue/black, and the RR is lt. GREEN/ black. They are in the purple plug at the BCM. Use all wires and diode isolate.
