2001 Silverado, Which DEI Module to use

I am starting to install remote start/ keyless entry systems and have had good luck so far.  My only problem has been figuring out which DEI modules to use to interface with them for the factory locks and factory alarm system.  So far I haven't been able to set up an account with DEI to get access to their techsoft software and am looking for another way to figure it out in the mean time.  I am now installing a remote start/ keyless entry system in a 2001 Chevy Silverado 1500.  It has passlock II so I am assuming that it needs a 555L for that but am not sure what it needs for the door locks... any help would be greatly appreciated

that should be all you need is the bypass and use the + door locks wires of the locks"Big" Mike
