97 Pontiac Transport alarm/remote start

I installed a starter/alarm on my 97 Transport. Can somebody tell me how to hook up the lock/unlock wires in my van? I have one pulse output (for lock)from my unit, but it takes two pulses to lock the van!

It only takes two pulses if one of the doors is open. The first pulse will tell the Body Control Module that you want to lock the doors. If you pulse the light blue wire in the driver's kick panel with a negative pulse once it will cause a chime to be heard. If you close all the open doors, the doors will lock after a few seconds. Double pulsing the door lock wire will lock the doors whether they are open or not. The white wire in the driver's kick panel is the negative unlock wire.sparky

The unit has a programing option to change the lock from 1sec to 3sec. Also, the unlock from one to two pulses. Anyway, having a 3sec pulse to lock the doors did not take care of the problem. Also, I tried to trigger the lt. blue wire on the passenger kick (with all doors closed), but neither one pulse nor 3sec pulse worked. Hitting the lock button twice triggered the panic mode. It sounds like the moduler needs a one second break between the two pulses. I need help!!! Thanks for your help.
