According to what I see its passlock II. You will need some kind of bypass for it. There are different ways. I believe the easiest is a product called PLDATA or it may have a different name now. You can do a search here on PLDATA or passlock II and come up with what you need. If indeed it is passlock II there is also a relay , resistor method but, there is much more labor involved. 555 modules could also be used.

Ahh there we go Kartune man was replying at the same time I was. The bottom of his diagram shows you bypass module notes when you click on it.

Kartune is there still a 1 wire PLDATA or something similar for this bypass?

Dude, use a 457GW. It will do your passlock bypass as well as the factory alarm interface, the door locks and the Domelight supervision. Its a DEI piece and the best way to do this truck from my experience.
