Dodge ram 1500 1997 door locks

I installed a R.S unit on this vehicle today and everything went fine. Except for the door locks that is. I have them unlocking from the remote(R.S. remote)but they will not lock. This vehicle does not have keyless entry on it. I am using relays in the reversal rest configuration. That will let the locks unlock. I cant fiqure out how to make them lock. I have tried the positive pulse on the lock wire and that wont do it. I have tried the reversal rest on the lock wire and it wont work either. the locks work fine from the switch aty the drivers door. Any info would be greatly appreciated on this matter. Thanks in advance.Brian

I have tried that and it works fine for the unlock. That configuration will not work for lock. I have tested my relays,power on all pins,the outputs from the unit,ect... The tech support I use is also stumpped. Any other ideas?Brian
