Factory arm/disarm wires??

This is what I think you should have:

• RS750 PINK wire ( FACTORY ALARM DISARM )--------> LIGHT GREEN/ ORANGE
• RS750 LOCK wire (+) polarity required ----------> ORANGE / PURPLE
• RS750 UNLOCK wire (+) polarity required-------> PINK/PURPLE

THe RS750 has alternating polarity door lock wires so attach so that it will output a (+) current to the listed wirs.

That setup is how I have it now minus the PINK wire going to the factory disarm (LT GREEN/ ORANGE). The biggest problem is the doors all lock but the factory won't ARM. I'm wondering if there is another wire that arms the system and locks the doors. Accoring to the Techsoft there's a POWER LOCK wire and a LOCK MOTOR wire, what's the difference? It'e even stranger because if I arm the factory before the AP I can still disarm it using the AP, even without anything connected to the factory DISARM yet.

Strange isn't it?

The point I’m trying to make isn’t getting across and I apologize because it’s probably because I typed so much that it got confusing. My bad.

My problem, RIGHT NOW, is I can’t ARM the FACTORY with the current setup (which is exactly how Jeff has it minus the Pink wire, which is for DISarm anyway). I don’t think it’s the AP because it locks all the doors, which means it’s pulsing that connection just fine. So the AP is working fine. I think, however, that there is got to be another wire that ARMS the FACTORY and it’s not the ORANGE / PURPLE. It seems as though the Techsoft is wrong in stating that the FACTORY will ARM with the door locks because I am locking all the doors but the FACTORY isn’t ARMING. Has anyone had any experience with 99 Durango’s or Dodge in general? I will connect the PINK wire once I get a chance. I don’t have a garage so I have to use my parent’s garage and I don’t want to keep bugging them. I was hoping to wait till I got a list of ideas and then go and try them all in one visit. I appreciate any help and thank you in advance.

Where all the trigger points closed when you tested it? doors, hatch, hood

All doors, hatch, and hood were closed when arming with the AP. You gave me an idea, which had me experimenting with it, and leads me to believe that there has to be another wire or something else that arms the system. Here’s why:

When I lock the doors using the power lock button on the door while the door is open and then close the doors, all the doors lock and the factory ARMS. If I do the same thing while the door is closed, it just locks the doors and DOES NOT ARM. There has to be a trigger or something else. Over the holidays I am going to take Jeff’s idea and connect the PINK wire to the factory disarm LT GREEN/ ORANGE. After reading the “2000 dodge ram 1500. confused” post I wonder if there needs to be a resistor on one of the wires. It seems strange because the Techsoft doesn’t say anything about any resistance on any of the wires. But the then if you look at the next year (2000) it says to use the resistors. This just gets stranger and stranger.  What do you guys think?

OK wired everything as Jeff stated but still have one problem. I still can't arm the factory. As I stated before, in the Techsoft for the 2000 Durango, it says that it needs a 647 ohm resistor for the arm on the LT GREEN/ ORANGE wire. I used 640 since that's the closest I could get with the resistors I had lying around (5% tolerance killed me). How sensitive are these systems because I was going to go to Radio Shack tomorrow and pick up some more resistors and try again. Also, how do you professionals connect resistors and still keep everything neat? Do you guys uses small circuit or bread boards or do you just connect everything in series and than just e-tape it all up (which is what I did)? I'm curious if anyone has any pictures of how they do it also. Thanks.

I think I'll also have to use the 1562 ohm on the disarm because right now the DOOR UNLOCK is what I think is disarming the factory. If factory is armed and I try to remote start, the factory gets triggered; horn starts honking, engine gets killed, and I think the headlight flash but I can't remember.
