1999 yukon weird door locks

Hi,I am installing a remote/start alarm in my 1999 yukon. I am far from an expert, but have done this before. My door locks are acting strange though. In the wiring diagram on this site there are different wires listed for door lock/unlock, drivers lock/unlock and passenger unlock. I only hooked up the alarms lock/unlock tiggers to the door lock/unlock wires and left the others alone. The doors lock and unlock just fine with teh remote the first couple of times. Then both the drivers door and passenger door stop working. The rear doors and hatch work all the time. Is this a matter of me needing to hook up the drivers and passenger lock/unlock wires? And if so, what do I hook them to? The same lock/unlock triggers from the alarm that I hooked up already to the door lock/unlock? Hope that made some sense and thanks in advance!!

they stopped working just with the alarm or did they stop working all together?
