2006 sentra drv prio locks

i've recenly installed a viper 160xvl in a 2006 nissan sentra, and hooked up just about everything on the car to the viper,  and now the customer wants to know if there was a way to have kept the drivers priority unlock like the factory remote did.  all of the wiring diagrams i can obtain does not show the wires for drivers priority,  how do i go about this when all of the drivers priority door locks i've done have only been when i program a data bus interface.  i know ill need relays, but how do i wire it in?  by the way the car does not have a factory alarm but it did have a module above the gas pedal that have door pin wires and horn wires and door lock/unlock wires where i did alot of attaching to.  and i threw  an xpresskit xk03 or xk05 which ever one it was to bypass the key and that works like a dream.

       thanks in advance for your time.
