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

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. The GMDL4 does not have an output for aftermarket door triggers. It is meant to arm and disarm the factory alarm, etc. As far as the horn honking twice after the key is removed, are saying that this just started happening after you installed the GMDL4?J Rilla

yes,it started to happen after the gmdl4 was installed ,called automobility,no retutrned call as of yet.

Thanks Jeff, have the passlock II bypass taken care of

Turning off ignition controlled locks should fix the horn honking twice problem. The 03's also have some buttons on the steering wheel that allow you to change a bunch of settings on how the truck works. I think changing some of those settings can also disable the beep.

are you talking about the factory keyless settings?
