 EXTRA INFORMATION
 NOTE *1 Use ORANGE/VIOLET for LOCK and PINK/BLACK for UNLOCK at the DRIVERS DOOR SWITCH. Use BLACK/WHITE for LOCK and PINK/BLACK for UNLOCK at the passenger front door switch. This vehicle requires (2) of part # 778 one for each door See DIAGRAM. TO AVOID INSTALLING RELAYS IN BOTH DOORS.... USE INTERFACE MODULE Part # XK09 or DB-ALL. These are combo modules that bypass the Anti-theft and enable the use of keyless entry without adding relays. To make a keyless entry system work you can create the circuit above using (2) #778 realys but it's recommended to use the XK09 or DB-ALL. NOTE *2 the YELLOW Parking light wire will require a (-) Negative thru a 1300 Ohm resistor and a extra relay part #775, to connect, See DIAGRAM. NOTE *3 this vehicle has 4 Door trigger input wires, the DRIVERS DOOR is a TAN/RED (-) at the DRIVERS DOOR LOCK SWITCH, the PASSENGER DOOR is a TAN/RED (-) at the PASSENGER DOOR LOCK SWITCH, the DRIVERS REAR DOOR is a TAN/ORANGE (-) and the PASSENGER REAR DOOR is a TAN/YELLOW (-) both are at the BCM (Body Control Module), when connecting to an ALARM SYSTEM you must BOTH DOOR TRIGGER wires and DIODE ISOLATE, to connect, See DIAGRAM NOTE *4 on the 4.7L engine, go to any coil and use any wire that is NOT DARK GREEN/ORANGE. On the 4.0L engine, use any wire with a TAN STRIPE at the coil pack NOTE *5 to DISARM the FACTORY ALARM SYSTREM requires a (-) NEGATIVE thru a 463 Ohm Resistor and an extra relay part #775, to connect, See DIAGRAM NOTE***** the BCM (Body Control Module) is located above the DIAGNOSTIC PLUG under the dash.
