Where is the sensor for the door open/key in ignition on 2005 Ram 1500 quad. I want to play CDwith doors open & not hear chime.

I want to be able to play music while the doors are open and the key in the igninion on accessory. Past autos had a button switch that could be forced closed one way or another while door was open. I
assume there is a hidded switch/sensor somewhere. How do I over-ride it.

In my 97 Ram (when I had it) I just found (under the dash) and removed the buzzer/chime module.

On my '99 Ram Quadcab it's a plunger on the verticle portion of the A-pillar and the chime doesn't sound when I have the key in the accessory position.

In the 3rd gen trucks, the sensor is in the door latch. For the '05 model, there's a four-pin connector at the latch itself. You're interested in the 20-gauge violet wire, which is the door ajar sense. This wire can also be found in a 10-pin connector under the dash, one row of 4 pins, one row of 6 pins. To help identify it, these are the colors of the pins:
1- violet (this is the one you want) 2 - light green/yellow 3 - tan/gray 4 - dark green/yellow
5 - dark green/light blue 6 - tan/orange 7 - pink/yellow 8 - orange/light blue 9 - red 10 - black/violet
What I don't know is whether the violet wire is grounded when the door is open or closed. You'll have to use a meter and figure that out. If it's grounded when the door is closed, then just tap that wire, and run it to a switch on the dash that will allow you to manually switch to ground.
If it's grounded when the door is opened, cut the wire and run both sides to a SPST switch. Turning the switch off will prevent the circuit from being grounded.

You always have the best information. Are you a Dodge technician or service manager?

Neither... I'm a computer geek. I just enjoy working on my vehicles. I find the smell of grease and the busted knuckles offsets the pocket protector and taped-up glasses. :)

Hey, so am I. I mostly work on the telephony, wireless and WAN infrastructure for an independent oil company, but do some work with our Windows servers and workstations. I like saving money on vehicle repairs/upgrades and since I have 3 I don't mind having one down for an extended period of time while I do it right. That and it gives me something to talk about with the real mechanics at my company.

When I replied, I was under the impression that the poster was asking about leaving the driver's door open. I now see that he probably wants to have any, or all, doors open without hearing the chime.
It's more work, but it still has to be done by spoofing each door ajar sensor, as the chime is integrated into the instrument cluster, and can't be easily disabled on it's own. In this case, one could obtain all four wires at the instrument cluster connector.
To remove the instrument cluster, remove the two screws that hold the cluster bezel in place. These are on the underside of the bezel, and you'll need a short, stubby phillips to get them out. Once the bezel is removed, four screws hold the cluster in place. Pull the cluster forward, and disconnect the electrical connectors.
Of the three cluster connectors, you're looking for the 26-pin gray connector. Pins 1-4 are the four door sense circuits (1 - violet, driver's door 2 - violet/gray, left rear door 3 - violet/yellow, right rear door 4 - violet/white, right rear door).
Again, depending on the operation of the door latch, you'll either need to tap into all four wires and switch them to ground, or cut all four wires and insert a switch into the electrical path. My guess would be that the circuits are grounded when the door is closed, but double-check just in case.
If they are grounded when the door is closed, resist the temptation to just tap all four to the same SPST switch. You'll disable you door ajar sensors completely this way, unless all four are opened. You need to use a 4-pole switch (probably need to go to an electrical supply place for this - not something Radio Shack would carry).
