03’hummer h2

Does anyone have info on the hummer h2? I'm installing a autopage750lcd/ with a automobility gmdl4,( the first gmdl4 I've used )when you turn the key to off ,the factory horn beeps 2 times. Is this normal? Also,where is the the best place to get the door trigger input for the alarm? is the gmdl4 supposed to  take care of that? Any help is appreciated.

Notes:
NOTE: This vehicle has the passlock II immobilizer system that, when adding a remote start, must be interfaced with.  *1 The driver door trigger is gray/black at the driver door module in the door. The RF door trigger is BLACK/ white at the passenger door module in the door. The LR door trigger is lt. blue/black and the RR is lt. GREEN/ black, they are in a harness in front of the fusebox leading to the BCM rear plug. Use all four wires and diode isolate each.  *2 The BCM (Body Control Module) is located behind the headlight switch.  *3 The PCM (Powertrain Control Module) is under the hood on the driver side.

You also need the PLDATA to bypass the Immobilizer of the Hummer.
