In your case look into the 1700(formerly 1701g1). It will passive lock the entire truck. The main difference between it and the 1701 is the remote start features if your adding RS or ditching the factory keyless.
The doorlock arm/disarming from the 330 will feed into to the 1700 and the 1700 will tell the truck to full lock and arm factory security. When you lock or unlock the truck via the factory remote the trucks wiring will tell the 330 to arm disarm. This should be an elementry install for the installers.....

 

Sorry for the repeated questions but I want to get it straight. I have factory key fobs and factory remote start that I am keeping. WIll the 1700 make the truck passive arm and disarm and lock all the doors including the liftgate. If so will I be able to disconnect that cable coming from the engine compartment to my drivers door? Thanks again!!
