Does anyone know how to wire the Intrepid 1999 4D SD for Power Lock Operations using the CrimeGuard 745i3 Alarm. The vehicle uses a single wire system Wht/Grn wire located in the kick panel. The alarm comes with a Doorlock Output Connector.

Unlock (+) or (-) Input (NO) Violet Wire, Unlock Output (COM) Blue Wire, Unlock Input (NC) Brown Wire, Lock (+) or (-) Input (NO) Vio/Blk Wire, Lock Output (COM) Grn/Blk Wire, Lock Input (NC) Wht.Blk Wire, and Pink Wire for Unlock#2 250mA (-) Output.

Who can tell me how to connect this to this vehicle. Please ...

A positive pulse through a 620 ohm resistor will lock the doors while a positive pulse through a 2.7 k ohm resistor will lunlock doors.

You will need to relays through the resistors values that mobiletoys2002 stated above. Go to this link for a relay configuration needed to make the locks work: https://www.bulldogsecurity.com/wires/images/chrysler1wirecars.htm

The CrimeGuard 745i3 comes with built in door relays. Does he still need to add additional relays? Just asking becaues I'm starting to install one.

Just to add to what mobiletoys2002 stated to gferguso ...... if the CrimeGuard 745i3 have relays that can produce a + output to the door locks them all you need to do is add the respective resistors inline of the wire. The only reason why you needed a relay configuration like the one I posted is to turn a (-) output to a (+) one that the door locks can use.
