Qualcomm wiring

Is anyone familiar with the wiring on a qualcomm? My message notification beep does not beep. I am assuming that there is a wire that is not connected. I can see the wiring harness and there are several wires that have been cut into. I could connect these wires and perhaps randomly find the correct one through trial and error, but I don't know what any of these wires do, so I am recluctant to connect any of them.

I was told that some of our trucks have a switch added that turns off the message beeper. Mine doesn't, this is why I am assuming that the wire is not connected.

 

Yes, mine has that also, but I am talking about the incomming message beep. That is seperate.

 

Your volume control, controlled the volume. It does not turn it on or turn it off. You can turn your volume all the way down and stick your ear by the keyboard and still hear the beep. If I wanted to, I could go into the keyboard and disconnect any button. Then the volume control wouldn't control the volume of that particular key. I am asking about the wiring for the incomming message beep, not it's volume, the fact that it get a signal at all.

 

It is not controlled by the company, unless they snipped the wire. I just need to know what color the wire is so I can splice it.

Yes, I have googled it.

 

I am not a company driver. The shop told me some units had a switch installed to turn off/on the message notification beep. I am assuming the wires were cut, but the switch was not installed.
