The (3) Plugs are WHITE, BROWN or TAN and LIGHT BLUE. The 4th Plug, a PURPLE is located on the Back of the BCM. NOTE *2 On BASE model vehicles the DOOR Triggers are at the BCM in a LIGHT BLUE Plug, the DRIVER DOOR is a GRAY/BLACK (-) Pin B4, the PASSENGER DOOR is a BLACK/ WHITE (-) Pin A5. On all other trucks these wires are in each DOOR MODULE in each door. On the 4-door the DRIVERS rear door is LIGHT BLUE/BLACK (-) Pin A3, the PASSENGERS rear door is a LIGHT GREEN/ BLACK (-) Pin A2 in the PURPLE Plug. When connecting to an ALARM SYSTEM, you must DIODE ISOLATE these wires, See DAIGRAM NOTE *3 The PCM (Powertrain Control Module) is located in the LEFT FRONT of the engine compartment to the left of the fan shroud. NOTE *4 this vehicle uses a Special Multi-plex Type Door Locking System that will require (4) Extra Relays Part # 775, to do the Door Locks, See DIAGRAM NOTE *5 when hooking up a REMOTE STARTER on a DIESEL, if the WAIT to START wire from the Remote Starter does not wait until the Light on the dash turn out before cranking, you will need to program in the 5,10 or 15 Second WAIT to START TIMMER in the Installation Manual. On some vehicles the Wait to Start Light on the dash is not a true (+)Positive or (-)Negative and the wire from the Remote Starter will not owrk. When this Wait to Start Timmer is programmed, disconnect and tape up the Wait to Start wire from the Remote Starter that is tied into the Wait to Start Light on the dash. NOTE *6 IMPORTANT !!!!! this wire MUST BE CONNECTED as IGNITION #2 for REMOTE STARTING!!!!!! NOTE *7 On DIESEL ENGINES the TACH is WHITE in the BLACK Bottom plug, Pin 37 on the HYBRID the TACH is in a GREEN Plug, Pin 35
