Ok I'll ask one more time and hope someone can give me definitive answer. I'm installing a DEI Valet 552T into an 2003 jeep liberty. Do I need to wire up external relays for the one wire lock system,if so can someone give me the diagram? I note that the dodge caravan diagram uses no external relays. Thanks for all the help.

Some installers use the quick & dirty method of jamming a wire under each of the power door lock relays on the "one wire door lock" caravans, but it creates it's own set of problems.

Notes:
NOTE: Jeep vehicles that use a gray ignition key have an immobilizer system
that needs to be bypassed when remote starting. Use DEI part number 555C or
555U. *1 Lock is negative trigger thru a 1.4K ohm resistor and unlock is
negative trigger thru a 426 ohm resistor. MUST use relays. *2 In the top
left corner in a black plug. *3 Parking lights is negative trigger thru a
910 ohm resistor. Headlights is negative trigger thru a 349 ohm resistor.
MUST use relays. *4 The driver door trigger is tan and the passenger door
trigger is tan/white, use both wires and diode isolate each. *5 The factory
alarm disarm is negative trigger thru a 473 ohm resistor. MUST use relay. *6
The BCM (Body Control Module) is attached to the left of the fusebox.
Connector 1 is a gray 26 pin plug, and connector 2 is a gray 22 pin plug. *7
The flip up glass pin switch is yellow/white in conn. 1, pin 9 of the BCM.
*8 On vehicles with the premium sound system, each speaker is individually
amplified.
