90 Dodge Ram door locks

I have a 90 Dodge Ram that we just installed a Python 460HP in.  We were installing the power lock setup and keep running into a snag.. After using the the diagrams for relays that DEI had the door locks will lock when the system is armed, a second or 2 passes and they unlock again.  After checking the wiring over and over again the installer and I decided lets try the DEI 451M module and see if that cures the problem.  Still the same thing.  Arm the system and it locks then instantly unlocks.  We checked our wiring and tried hooking the module directly to the battery to make sure it wasnt getting a weird signal when armed. We reprogrammed the alarm to make sure it was set for active locking, not passive and we changed the lock pulse setting from .08 to 3.5 and they still unlock as fast as they lock.  The shop and I are both stumped now.   The truck had a audiovox alarm system in it before with a door lock module and that worked great until the alarm itself went bad and after looking at the way the old one was wired its almost identical.   

Is somthing wired weird that we are overlooking?

This is how I hook it up:

The truck is a 1990 Dodge D-250 LE.  It has factory power locks.  The Audiovox system came with a module that had 7 wires coming out of it.  Ground, Power, 2 wires for lock and 2 for unlock and one that went to the alarm module.  The orange wire was cut and the pink wire cut to hook into the module.  The Audiovox also had somthing in the module that when armed held the door locks in the lock position like you were holding the switch in the lock postion for a moment until the system fully armed.  Same thing when it was unarmed.   This python doesnt do that. 

On your Python:
