Is there a wire that I can connect to that will just be hot if a door is open, and not if it isn't?? I can't find one and the dome delay is causing problems with my remote start install.

 GRAY/BLACK at the courtesy light under the dash or the light over the driver's side door to catch all doors and the rear hatch. The seperate doorpins are: GRAY/BLACK-driver's door (located in driver's door), BLACK/ WHITE-passenger door (located in passenger door), LT.BLUE/BLACK-left rear door, LT.GREEN/ BLACK-right rear door (both found at the fusebox under the rear seat on the driver's side. All wires are negative (-) polarity.

Just a tip.....try to keep all your posts on one thread...it makes it easier for people to help you.

If the gray/black dome light (+) wire is causing problems for you then the only way around it is to either connect individual door triggers (as mentioned above LF, RF are at the door module(the switch with locks/windows/mirrors)), or to use a data interface module such as Bypasskit's GMDL-BP which will give you a (-) door trigger output that is active when the LF door, RF door, rear hatch, or hatch glass is opened.  With the GMDL-BP you would still have to connect to the rear door wires, but it would save you from wiring inside 3 doors. 

What are you installing that you're having problems with? You didn't mention if it was just a remote start or an RS/Alarm combo unit.

It is a remote start/alarm combo. I am using the GMDL BP, but the door trigger output is always showing ground and won't change. Does that work for this model?

OK, I have connected the door trigger on the rs/alarm to the pink/white from the GMDLBP, then connected the pink on the GMDLBP to the domelight, and the same thing happens. When the door is closed and the alarm is set, it will work fine until the domelights dim out, then it sets off the alarm.

Are you using the (-) door trigger input of the alarm....almost sounds like you are using a (+) input.

According to the alarm manual it can be either one. There's only one input.

Disconnect the GMDLBP's pink from the car's domelight.

As others have said, the GMDLBP's pink white will give you a non-delay-affected trigger for the two front doors, and the rear hatch.

Depending on your preference, you could either wire in directly to the two rear door triggers, or even skip them if it's not important to you.

If your Trailblazer has a factory alarm, you might consider just relying on that to protect the two rear doors, or you could just run a wire back there (I think the triggers are under the rear seat).

You can catch the rears in the boots, so one might think the could be found in the running board area.

lt.blue/black, lt.GREEN/ black  RL /  RR

OK, I will try that and let you know. Thanks for all the help.

OK, now the alarm goes off as soon as I set it. From what I can tell, the pinkwhite gives off a ground when the door is open. Is there anyway to have it give off 12 volts WITHOUT using a relay?

How exactly does your alarm know what the polarity of the door trigger is going to be? Is there a jumper somewhere that needs to be switched?

I agree there is no way your door trigger wire on the alarm is going to use the same wire unless there is a polarity switch or a setting in your programming. On every trailblazer i have ever done i have not used the door trigger wire on the bypass but just connected the gray/black positive in the truck directly to the alarm's positive door trigger, then program for the delay. I do this because i have had issues with our DEI bypasses(1700g and 457g) working correctly and not showing me an open trigger when there isn't...

OK, I found the jumper, but the delay is still killing me. The alarm is supposed to have a programming mode, but I can't find out how to get in it. I just found out that the manual I have is not for this alarm because some of the connectors it describes aren't there. Gone to do some more troubleshooting

OK, I have decided to come off of each door and diode each trigger. Question #1, where do I find these diodes and what rating do they need to have?? I have called RadioShack and they are giving me a lot of terminology that I don't understand. Can someone walk me through what I need to do here?

cant a dei 1700G1 be used on the 04 trailblazers? This should not only work the doorlocks, but also give you a proper door trigger signal all through the data port, and bypass the passlock. I think the extra money for the bypass would be worth more than the extra hassle you are going through.
Just my .02

I have a GMDLBP that is supposed to have a proper working door trigger, but it doesn't work.

oh ok... sorry, i wasnt familiar with that bypass. I would probably just run the seperate door triggers at each door. It may be time consuming, but atleast you know it will work properly.

In the hinge of the door, I have a grey wire and a black wire, but no grey/black. Which one am I looking for??




Posted By: offroadzj

To avoid dome light delay, use the separate door trigger wires. The LF door is gray/black (-) at the driver door module in the door. The RF door is BLACK/ white (-) at the passenger door module in the door. The LR door is lt. blue/black (-), and the RR door is lt. GREEN/ black (-). The rear door trigger wires are at the fuse box under the left rear seat. Use all four wires and diode isolate each.

You may also be able to get the wires in the door jam, but i am not 100% sure

So what system you installing here?

The biggest piece of Chinese junk EVER!! I finally got it to work, but it is still trying to do crazy stuff.   It's called an Inwell. If they are ever giving any away for free, get a bunch and throw them in the deepest river you can find.

I don't understand. The piece you're installing doesn't have a negative door trigger input, only positive?

You said the GMBLBP makes a ground when the doors are open...that's normal.

I supposed if the alarm only has a positive door trigger input, you could invert the GMBLBP's output with a relay, to give the alarm a positive when the doors are opened.
