Notes:
NOTE: Some models of this vehicle are equipped with PATS (Passive Anti Theft System). Use DEI module 555F to over-ride during remote start.  *1 Power this wire if vehicle is equiped with only rear anti-lock brakes. Vehicles with all wheel anti-lock brakes do not have this wire.  *2 Negative pulse, type 'B', on keyless entry models. Five wire, type 'C', on non-keyless models, mastered from the driver switch.  *3 May also be found at trailer connector next to diagnostic connector under dash.  *4 If equipped with autolamps.  *5 The BLACK / YELLOW catches the drivers door and the BLACK/ pink catches the passengers door. The wires are found in there respective door harnesses. On the Super Crew the rear door trigger is BLACK/ lt. blue low in the driver kick panel. Use all wires and diode isolate each. See direct fax document #1076 for wiring information. Both wires may also be found at the GEM module located above the fuse box. On models without a dome light delay use ORANGE / lt. green (-) at the light switch.  *6 Arms when locked with the door open. To simulate, send a negative trigger to the lt. blue/white wire at the RAP module, located behind the light switch, while locking.    *7 Tach wire: on the 4.2L it is a dk. blue/lt. green at the coil pack on top of the motor. On the 4.6L go to any of the 8 ignition coils and use the wire that is not RED / green. On the 5.4L it is a lt. GREEN / WHITE at the coil on the passenger side of the motor between the fuel injectors.  *8 The GEM in this vehicle shuts down after the doors have been locked for a certain time period, to 'wake-up' the system refer to directfax document #1093.

Is up to the installer to test all wires with a DMM whenever possible.
