What do you guys use for door trigger on the 03+ GM trucks? The truck in question is a 2006 2500HD and I used a Peripheral PGMDLBP. I used the gray/black dome supervision on the door input from the alarm (not from the databus module), but the owner is particular in that if the dome overide button is off, it does'nt trigger the doors.

the gray/black shows that its the actual door pin and not the dome light. you have to go straigh tto the BCM (PITA) but it might b your only solution. im not sure what wire it is, but i beleiev Chris posted some info about this.

I think the bypass kits amdl should do the trick.

The output from the GMDLBP will work regardless if the dome light overide is on or off. The only other way to do it is to diode isolate the negative doorpin input wire and run one into each front door. The circuit only exists inside the doors between the switches and the door modules.

So instead of using the door trigger from the alarm, use the door trigger output from the PGMDLBP and it'll work regardless of the dome override button, correct? Thanks for all the replies so far....

I just checked the diagram from the PGMDLBP. I'm guessing the door trigger input (pink/white) should go to the - door trigger from the alarm, right? I haven't done one of these trucks in a while so I need some refreshing.

Maybe I need to clarify this. If you need a input for your alarm that triggers when a door is open, use the pink/white wire. It is a negative trigger so hook it up to the alarm's negative doorpin input. If you want the interior lights to come on when the alarm is disarmed, the GMDLBP should do this automatically, but the dome light overide switch must be off to allow the dome lights to work. If for some stupid reason the owner wants the dome light overide on and still wants illuminated entry, then you will need a relay. The output from the alarm that is designed for illuminated entry will trigger the relay. The relay will have to be wired to connect to the dome light wire directly, bypassing the BCM. Connecting to any of the switched wires on one of the dome lights should turn them all on, as they are usually in a parallel circuit. I should also mention that the GMDLBP only senses that the front doors are open. If the truck is a crew cab with four separate doors, you will need to diode isolate the front doors into each of the rear doorpins wires at the BCM.

The rears are GREEN/ black and blue/black on the back plug of the bcm.

I just want the alarm to trigger from any of the doors opening. Not worried about illuminated entry. When I mentioned dome supervision, I intended for the alarm to trigger when it saw the domelight come on. So the pink/white from PGMDLBP is going straight to the negative door trigger input from the alarm.

Correct, provided the truck only has 2 doors. The pink/white goes to ground when either front door is opened. It derives this from the Class II data bus.

Nope, it's a crew cab. So the front doors are covered by the PGMDLBP, and the rear doors are diode isolated and go to the green from the alarm?

Let me clarify that: The rear doors (GREEN/ black and blue/black on the back plug of the bcm) are split from the green door trigger output of the alarm?

And with it hooked up as above, will the dome override switch position affect the rear doors? Sorry for all the questions, just trying to figure it out so I can get this guys truck done. The dome override switch is throwing a kink in the whole thing....

You have to diode isolate both wires to each rear doorpin as well as the output from the GMDLBP module. Connect the alarm's negative doorpin input to three diodes (bands facing away from alarm)and then connect one to the RR doorpin, one to the LR doorpin and one to the GMDLBP's doorpin output. The dome light overide affects all doors. It shuts the dome light off from any door opening.

Got it, thanks... If the override affects all doors, does this mean that the override can affect the door trigger actually triggering the alarm? That's gonna work, but I'm just curious. Thanks a bunch for your help...

nope, you are going straight to the pin. the pin controls domelight. if any door is open the alarm will trip
