2003 Silverado SS door triggers

<>

I have a 2003 Silveradoo SS extended cab and I have been reading a lot about the 2003 Silverado door triggers and the wiring colors for them. What I found out is that the trucks are under two types. The base model (standard cab) and the four door (true four door / not extended cabs in my book). I have not found anywhere anything about the extended cab Silverado specifically. Do the extended cab 2003 Silverados rear doors (the rear two doors open backwards) have any door triggers in them? If they do, can someone tell me where they are physically located and what color wires they would have? And one last thing, where are the door triggers physically located for the driver and pass doors.

I need to know for sure because the professional installer (so he calls him self) is trying to tell me that he can not get the Clifford Matrix RSX 3.5, with 555L and 456G modules, wired in a way to give the door open indication on the remote when you arm the alarm and have one or more doors open. I told him to use the wires from the door triggers and use diodes to keep them separate. He is trying to tell me that he can only get the signal from the dome light.

Thanks in advance, Edessa.

Hi edessa, Your professional installer (or so he calls himself) is right! The door pin switch wires are in the individual front doors and send this info via a class 2 data line to the BCM. To get door trigger wires, he'd have to go into the doors (about one hour work if you want to pay the extra) but it goes contrary to the idea of using a 456G data module! The domelight wire inside the vehicle is a positive signal which feeds the domelight. If he connects to this, you'll get a "door open" message on your transmitter everytime the remote starter times out. Not good. Prepare your future. It wasn't the lack of stones that killed the stone age.

The door ajar wires are grey/black for the driver's door and BLACK/ white for the passenger's door. There are no wires or switches for the the rear doors in an extended cab model. You can't open those doors unless the front ones are opened first. If the truck is a crew cab (four doors each with it's own exterior handle) then there are doorpin wires for those at the BCM under the steering column. The front door ajar wires are found at their respective door modules inside the doors. The door panels come off in less than 5 minutes. The wires don't come out of the door, but are changed into data by the door modules and then that signal is sent to the BCM. Be very careful with using data modules that claim to read the front doors open data signal. Most don't work and a lot of GM vehicles don't trigger the dome lights to come on unless the light sensor in the vehicle detects low ambient light conditions. The best way is to run wires into both front doors and diode isolate them.sparky

You don't need to worry about the rear door triggers, since it is impossible to open those doors without opening the front doors first. The front door trigger wires are as follows: grey/black (L) BLACK/ white (R) The installer could go into each door and use those wires, but it will probably take over an hour to do it. I would charge you extra. The 456G doorlock module has an input for the door trigger on it. It then has an output that connects to the alarms door trigger input. When the remote start times out (after the programmed time or if you shut it off by remote), the truck turns the domelight on for a few seconds. The 456G automatically disconnects the door trigger input to the alarm when the remote start times out to prevent the alarm from being triggered.   Using the 456G for the door trigger makes the installers life much easier. I'm not 100% positive on the following, but I think I'm right. When you exit the truck and close all the doors the domelight stays on. When you hit lock on the remote, the domelight shuts off. Alarm is happy because it sees the door closed. If a door is open, your remote will beep at you that the door is open. Lets say your unloading things from your truck and you have the doors open. Your running back and forth from the house taking a few minutes. The truck automatically shuts off the domelight to prevent the battery from draining.   Now is when things get weird. If you have passive arming turned on, the alarm will passive arm since it sees the door open, which is probably not what you want. Other possibility is you grab the last thing in your truck, and close the door as you walk away. You hit lock on the remote and go in your house. Only problem is you didn't close the door all the way. The remote never notifies you the door is open, since the domelight has been off for a few minutes now. Minor issue....yes. If it was my truck, I would go in each door for the door triggers. For a customer, I'd probably go to the domelight unless they want to pay me for the extra hour+ to go in each door.

sparkie, you beat me to it while I was typing.

Hey jworm! The module you mention. Does the domelight input go to the actual dome light bulb wire? If it does then the module won't work if the dome light overide switch is used or if the dome lights aren't enabled by the ambient light sensor as I mentioned exists in some GM vehicles. Am I correct. I am curious to know. sparky

i've got the same system and if you dont go inside the doors then you'll never get the system to show open door on the remote using the 456G module...also as sparkie mentioned if you forget and leave dome light override on, it shuts down that input... i went inside the doors but most installers wont unless you're willing to pay extra to have them do so....

Birdslam yes you take out all the screws and pry on the clips. They make a really bad noise when you pull on them but you are not hurting anything.
